Updated on 1/13/2023. Removed privacy options for features no longer available, added new screenshots, and updated instructions on setting currently available privacy options.

Privacy issues and privacy controls on Facebook are ever-changing, and I've read through hundreds of comments and emails from our readers who are confused about how to keep their information private and what specific Facebook privacy settings actually do.

For example, when you post a picture of your kids at a family gathering, which of your Facebook friends can share it? What private information are those Facebook game apps collecting for "third-party uses"? How do you make sure that your live video stream is seen only by the people you choose?

Every action you take on Facebook has privacy and sharing implications that you need to consider before uploading that next selfie. However, it takes a lot of time to check all of your Facebook settings, and, even then, it's not always clear what the right choices are to ensure your privacy is protected.

I just went through a complete review of every Facebook privacy setting currently available (Facebook is constantly making changes, and I will continue to update this article). My recommendation for most people is to use a computer and start with Facebook's "Privacy Checkup", which covers many of the key areas. In this guide, I will walk you through how to access the Privacy Checkup, and break it down setting by setting to make it easy for you to decide what you should change. I also have direct links to "hidden" Facebook settings that aren't part of the standard Checkup but have important privacy implications.

To get to Facebook's Privacy Checkup, open the menu (your profile photo with the dropdown arrow in the top right on computers or triple bars in the mobile app), select "Settings & Privacy," and then select "Privacy Checkup" (for computers) or "Privacy Shortcuts" and then "Take a Privacy Checkup" (in the mobile app). Here, you can find an easy-to-follow walkthrough of your current settings as they pertain to:

• Who can see what you share
• How to keep your account secure
• How people can find you on Facebook
• Your data settings on Facebook
• Your ad preferences on Facebook

Who can see what you share on Facebook

In this section, you can check your profile information, settings for Posts and Stories, and settings for blocking people. You can limit your audience to just you, your Facebook Friends, or Custom lists that you create. For instance, you can create a family list, acquaintances list, or work list. Go to facebook.com/friends and click on Custom Lists to get started.

Choose who sees your profile information

Here you can see the privacy settings – who can view your information – for your phone number, email addresses, birthday, hometown, relationship status, and other personal details about your life.

Set email addresses associated with your Facebook account

Under emails, it will show all email addresses associated with your account and who can view them. Email addresses are important because you can use any of them to log into your account with your Facebook password. Be careful to remove any old email addresses or ones where you're not using secure passwords, because if that email address is hacked, it could compromise your Facebook account, as well.

For email addresses that you still have but don't want others to use or see, you can limit the audience to “Only me.” If you find an email address that you don't want to be associated with your account, you can't delete it through Facebook's Privacy Checkup. If you want to delete an email, go to www.facebook.com/settings?tab=account. Under General Account Settings, clicking on Contact will reveal a list of email addresses that you can make your primary email or delete.

Set your birthday and who can see it on Facebook

For your birthday, you can choose to share your whole birthday or just the month and day. That way, your Friends can wish you a happy birthday on Facebook on your special day without necessarily knowing your exact age. Birthdays are sometimes used as a security verification for various services, so you want to keep it as protected as possible.

You can also set your birthday by going to go to your profile page (you can access it by clicking on your profile photo in the side menu bar) and clicking on "About" (or "See Your About Info" in the app). In the "Contact and basic info" section (or "Basic Info" section in the app), you can change the settings for your birthday.

Set your hometown and current city on Facebook

For your hometown, this setting only affects what your Friends can see. Advertisers and others may still access this information, especially if you are using the Facebook app, which tracks your location automatically.

You can also set your birthday by going to go to your profile page (you can access it by clicking on your profile photo in the side menu bar) and clicking on "About" (or "See Your About Info" in the app). In the "Contact and basic info" section (or "Basic Info" section in the app), you can change the settings for your hometown and current city.

Set your relationship status on Facebook

If you have set a relationship with another Facebook user, it will be shared unless you set it otherwise.

You can also set your birthday by going to go to your profile page (you can access it by clicking on your profile photo in the side menu bar) and clicking on "About" (or "See Your About Info" in the app). In the "Contact and basic info" section (or "Basic Info" section in the app), you can change the settings for your relationship status.

Set your work history and where you went to school

You can choose to share your work history and where you went to high school, college, and graduate school. Each of these entries has its own audience setting, from "Only me" up to including "Everyone." This setting may help old friends find you, it also may be used for targeted advertising.

You can also set your work history and where you went to school65 by going to go to your profile page (you can access it by clicking on your profile photo in the side menu bar) and clicking on "About." In the "Work and Education" section, you can change the settings for your work history and where you went to school.

Choose who can see your friends list on your profile page

If you want to limit who can see your list of Facebook Friends, you can set your audience from "Only me" up to including "Everyone." Since friend lists can be used for phishing and to create fake profiles, I highly recommend setting this to Friends only.

You can also choose who can see your friends list on your profile page by going directly to www.facebook.com/settings?tab=privacy, and you'll find the option in the "How People Find and Contact You" section.

Choose who can see the people, Pages, and lists you follow

Facebook lumps people, Pages, and lists that you follow together. So it's all people, Pages, and lists or nothing. You can set your audience from "Only me" up to including "Everyone." Consider whether there are any sensitive Pages you follow that you wouldn't want the world to know about.

You can choose who can see the people, Pages, and lists you follow by going directly to www.facebook.com/settings?tab=privacy, and you'll find the option in the "Your Activity" section.

See how other people view your Facebook profile page (Not part of Privacy Checkup)

If you're curious about what your Facebook profile looks like to other people, you can go to your profile page (you can access it by clicking on your profile photo in the side menu bar) and click on the triple dots next to the "Edit Profile" button and select "View As."

Choose who can comment on your public profile pictures and other public profile information (Not part of Privacy Checkup)

When you post a new profile picture or change other information that you've made available to "Everyone," you can still limit who can like or comment. If you want to limit what random people can say on your profile pictures, go to www.facebook.com/settings?tab=followers, and you can select "Friends," "Friends of Friends," or "Everyone."

Add more information to your Facebook profile page (Not part of Privacy Checkup)

To add more information to your Facebook profile page, go to your profile page (you can access it by clicking on your profile photo in the side menu bar). In the About tab, you'll see all of the categories of information that you can add your religious views, political views, your social channels, websites, primary language, nickname, birth name, and more. For each piece of information, you can see your audience from "Only Me" up to including "Everyone." Most of this stuff seems to serve little purpose except for use in targeted advertising.

Choose your audience for Posts and Stories

In this section, you can select who can read your future posts and stories, as well as read your prior posts on Facebook.

Choose who can view your future posts

"Future Posts" is where you set your default audience for your regular posts, including text posts, photos, and videos. These are the normal Facebook options for "Friends," "Friends of Friends," "Everyone," or "Custom." My advice is to keep it to Friends unless you are trying to promote yourself to everyone or you have a specific need for a Custom setting (e.g., to exclude a toxic friend or relative).

You can choose who can see your future posts by going directly to www.facebook.com/settings?tab=privacy, and you'll find the option in the "Your Activity" section.

You can always override your default setting for a specific post at the time you create it by clicking on the downward caret next to the audience and selecting a new one.

Choose who can comment on your public posts (Not part of Privacy Checkup)

When you create a public post, everyone on Facebook can see it. However, you can limit who gets to comment on your public posts. Go to www.facebook.com/settings?tab=followers, and you can select "Friends," "Friends of Friends," or "Everyone."

Choose additional people who can see a post you are tagged in (Not part of Privacy Checkup)

If someone tags you in a post, you can choose whether to allow additional people to view the post (e.g., your Facebook Friends) if they aren't already in the post's audience. You can also control how these posts appear on your Facebook profile.

You can choose who can see posts you're tagged in by going directly to www.facebook.com/settings?tab=timeline, and you'll find the option in the "Tagging" section.

Choose who can post on your profile (Not part of Privacy Checkup)

You can limit the people who can post on your profile page from "Only me" up to including "Everyone." Go to www.facebook.com/settings?tab=timeline, and you'll find this option in the Viewing and Sharing section. My advice is to keep it to Friends or Friend of Friends, unless you enjoy random comments from strangers.

Choose to hide comments with specific words on your profile page (Not part of Privacy Checkup)

If you're concerned about crude language appearing on your profile page, you can add up to 1,000 keywords that will cause a post to be hidden. The post will still remain visible to the people who posted and their Facebook Friends. Go to www.facebook.com/settings?tab=timeline, and you'll find this option in the Viewing and Sharing section. Though you're probably better off just limiting who can post to your profile above to Friends (unless your friends are the problem!)

Choose who can see what others post on your profile page (Not part of Privacy Checkup)

You may not want everyone to see what other people are posting on your profile page. You can change the audience from "Only me" up to including "Everyone." Go to www.facebook.com/settings?tab=timeline, and you'll find this option in the Viewing and Sharing section.

When you are tagged in a post created by someone else, choose who can see the post (Not part of Privacy Checkup)

If you are tagged in a post by someone on Facebook, some of your Facebook friends may not see the post because they aren't in the audience designated by the person who created the post. You can choose to make posts that you are tagged in visible to all of your Facebook Friends or a custom group of your Friends. Or, you can choose not to expand the audience by selecting "Only me." Go to www.facebook.com/settings?tab=timeline, and you'll find the option in the Tagging section.

Choose to review posts you're tagged in before they appear on your profile (Not part of Privacy Checkup)

If you are tagged in a post, the post defaults to automatically showing up on your Timeline. I recommend you choose the setting to review the posts before they appear. Go to www.facebook.com/settings?tab=timeline, and you'll find the option in the Reviewing section.

Find and remove old posts from your Timeline that you were tagged in (Not part of Privacy Checkup)

Ever been tagged in an embarrassing photo from two decades ago uploaded by that old college classmate? You can remove these tagged items by going to your profile page (you can access it by clicking on your profile photo in the side menu bar) and click on Manage Posts.

In the box that pops up, click on "Filters." In the Post Filters box, you can select "only show posts I'm tagged in." You can choose to hide the posts or remove the posts. First, go through and select the posts where you want to remove yourself (untag yourself), click "Next," and select "Remove Tags." Then go through and select the posts that you want to be able to view but don't want others to see in your Timeline, click Next, and then select "Hide Posts."

Choose to review tags people add to your posts before they appear on Facebook (Not part of Privacy Checkup)

Posting an old photo from a school or work outing? Once you share it, your Facebook Friends may want to tag more people in the photo. By default, your Facebook Friends can add tags. However, you can choose to review these tags before they appear on your post. Go to www.facebook.com/settings?tab=timeline, and you'll find the option in the Reviewing section.

Choose who can view old posts

The setting for "Limit Past Posts" only applies to Public posts. You can choose to restrict the audience to only Friends or Friends of friends. When you limit your past posts here, it will apply to ALL of your public posts. We recommend the Friends setting over the Public one. When set to Public, all of your posts can be seen by anyone on or off Facebook. Unless you're a celebrity or running a page that is used to generate interest in a business that you run, you will likely want to keep your activity restricted to those you have Friended. Keep in mind that anyone who is tagged in your posts and their Facebook friends may still be able to view these posts.

You can choose who can view old posts by going directly to www.facebook.com/settings?tab=privacy and clicking on "Limit Past Posts" in the "Your Activity" section.

Choosing an audience for a single old post (Not part of Privacy Checkup)

If you want to change the audience for specific posts, you'll have to go into each post individually to change it. You can change the sharing settings of any individual Facebook update by clicking on the triple dots, then sharing button to the left of the Post button.

Choose who can view your Stories

For "Stories," which are visible for 24 hours, you can limit your audience to your Facebook Friends or create a custom list of people with whom you want to share your stories. You can only set your default story audience within the Privacy Checkup. For individual stories, click on the cog next to "Your Story" when you create a story, and you'll find the option to change your story audience for that story.

Choose whether you will allow others to share your posts to their Stories (Not part of Privacy Checkup)

If you tag someone in any post, that person can share it to their Story, along with your full name and a link to your post. You can disable this feature by going to www.facebook.com/settings?tab=timeline, and you'll find this option in the Viewing and Sharing section.

Choose whether you will allow others to share your public Stories to their own Story (Not part of Privacy Checkup)

If your Story is public, you can allow others to share your Story to their own Story, along with your full name and a link to your original Story. Go to www.facebook.com/settings?tab=stories to make your choice.

Choose whether other people will see the total number of reactions to posts you share (Not part of Privacy Checkup)

If you don't want other people to see the number of reactions to your posts, you can turn off showing post reactions. Go to www.facebook.com/settings?tab=reaction_preferences and toggle off "On your posts" in the "Hide number of reactions" box.

Block a person from interacting with you on Facebook

Blocking a person means that you are invisible to that person on Facebook. So if a mutual Friend tags you in a post, that person won't see the post. If you comment on a mutual Friend's post, that person won't see the comment. There are a few exceptions. If you both use a Facebook app or game or if you've both joined a group, the blocked person could see you. And, the person you block won't disappear entirely from your view. If a mutual Friend posts a photo and tags the blocked person, you may still see it on your Friend's timeline.

To block someone, go directly to www.facebook.com/settings?tab=blocking

Block just messages and video calls (Not part of Privacy Checkup)

If you just want to stop a person from sending you messages or attempting to connect via a video call in Messenger, you can go to www.facebook.com/settings?tab=blocking and add their name in the "Block messages" box.

Block just app invites (Not part of Privacy Checkup)

If you just want to stop a person from sending invitations to try an app (occurs when one of your friends is trying to get free stuff in a game), you can go to www.facebook.com/settings?tab=blocking and add their name in the "Block app invites" box.

Block just event invites (Not part of Privacy Checkup)

If you just want to stop a person from sending event invitations, you can go to www.facebook.com/settings?tab=blocking and add their name in the "Block event invites" box.

Block apps (Not part of Privacy Checkup)

If you want an app to stop contacting you and prevent the app from obtaining non-public information about you through Facebook, you can go to www.facebook.com/settings?tab=blocking and add the name of the app in the "Block apps" box.

Block Pages (Not part of Privacy Checkup)

If you want a Page to stop interacting with your posts or be able to like or reply to your comments, you can go to www.facebook.com/settings?tab=blocking and add the name of the Page in the "Block Pages" box. You will be unable to post to the Page's Timeline or message the Page. And, if you currently like the Page, blocking the Page will automatically unlike and unfollow the Page.

How to keep your account secure

In this section, you can change your password, turn on two-factor authentication, and get alerts when there is an unrecognized login to your account. If you already have two-factor authentication turned on and alerts are set for unrecognized logins, you'll receive the message that "You're all set. No security actions are recommended at this time."

Use a strong password

Do you have a strong password for your Facebook account – one that is unique to Facebook and at least 12 characters, including upper and lower case letters, numbers, and special characters? If the answer is no, you should consider upgrading to a strong password. To ensure you remember your new strong password and to make it easier to use strong passwords going forward, we recommend using a password manager. We are fans (and users) of Dashlane and 1Password.

Turn on two-factor authentication

A strong password is essential, but that's not enough if it's compromised in a data breach or you are tricked into giving it away in a Facebook credentials phishing attack. That's where two-factor authentication comes in. When two-factor authentication is turned on, anyone trying to log into your account from a new device or browser would need to provide a one-time-use code delivered via an app, text message, or email. I highly recommend turning on two-factor authentication.

You can also go directly to www.facebook.com/settings?tab=security and find the option to turn on two-factor authentication in the "Two-Factor Authentication" section.

You should also check the list of devices and browsers that don't require a code when you log in to ensure there aren't any of your old devices on the list. To check this, go to www.facebook.com/settings?tab=security, and in the Two-Factor Authentication box, click on "View" next to "Authorized Logins."

Receive alerts when there is an unrecognized login to your Facebook account

Login alerts can be sent any time that you log into your account from a device or browser that you don't usually use. I highly recommend turning on alerts. You can choose to have alerts sent via Facebook, Messenger, email, or any combination of these methods.

You can go directly to www.facebook.com/settings?tab=security, and click on "Edit" next to "Get alerts about unrecognized logins" in the "Setting Up Extra Security" section.

You can see where you're logged into Facebook – the device and physical location – by going to www.facebook.com/settings?tab=security and checking the box entitled "Where You're Logged In." If you see a suspicious login, you can click on the triple dots next to it and "Log Out" that device.

How people can find you on Facebook

This section walks you through the ways that you can limit how people can find you through search engines (like Google), or with your phone number, email or name on through Facebook.

Choose who can send you a Friend request

You have two options for limiting who can send you a Friend request: Everyone or Friends of friends. Unless you're being inundated with requests or don't want to be found, I recommend leaving the setting on Everyone so legitimate people who want to connect can.

You can access this directly by going to www.facebook.com/settings?tab=privacy, and you'll find the option in the "How People Find and Contact You" section.

Choose whether people can use your phone number or email to find you

People can look you up on Facebook with your phone number or email address, even if you have them hidden on your profile. This method makes it easy for people you know to find you, especially if you have a common name on Facebook, like Jane Smith. Have the settings option set to "Everyone" or "Friends of Friends" if you want people to find you using your email address or phone number. Or, you can also choose to fully hide your email addresses or phone numbers by selecting "Only me" as the audience. The settings you choose apply to all of your phone numbers or all of your email addresses.

You can access this directly by going to www.facebook.com/settings?tab=privacy, and you'll find the option in the "How People Find and Contact You" section.

Choose whether your Facebook profile appears on search engines

You can find your Facebook profile on search engines like Google. If you don't want your Facebook profile coming up in search, you can toggle this setting off in the privacy checkup or you can access it directly by going to www.facebook.com/settings?tab=privacy and looking in the "How People Find and Contact You" section.

Your data settings on Facebook

Facebook makes it easy to log into other websites and apps with your Facebook account. If these conveniences are too invasive for you, here's where to turn them off.

Using Facebook to log into apps and websites

Instead of creating a new username and password for an app or website, you may have used your Facebook account. If you no longer use the app or website, it's a good idea to remove the connection. However, some apps and websites may hold valuable information in your account. When you remove the connection to your Facebook account, you lose access to your account.

Remove login with Facebook for specific apps and websites

To see a list of your Facebook logins, go to www.facebook.com/settings?tab=applications. Click on the "View and Edit" button next to any app and website logins you want to keep to check what data the app or site is collecting and see what information is required for the connection and what is optional. If you want to delete your connection, click on "Remove" next to the website or app name. In the pop-up window, you'll be given the option to "delete all of the posts, photos, and videos that the site or app has posted on your Timeline" and/or "Allow Facebook to notify [app name] the login was removed." This second option may enable you to recover data in the account you created with your Facebook login.

Turn off login with Facebook for apps, websites, and games (Not part of Privacy Checkup)

You can turn off the ability to use Facebook to log into apps, websites, and games. Go to www.facebook.com/settings?tab=applications, and in the Preferences section, click on the button next to "Apps, Websites and games."

Turn off game and app notifications (Not part of Privacy Checkup)

You can turn off annoying notifications for game requests from friends, game status updates, and app notifications. Go to www.facebook.com/settings?tab=applications, and in the Preferences section, click on the button next to "Game and app notifications."

Your ad preferences on Facebook

Facebook will show you ads – that's how they make their money. It's just a question of whether those ads will be targeted to your demographics and interests or non-targeted (and, perhaps, less relevant to you).

Hide ads from specific brands (Not part of Privacy Checkup)

If you're tired of being inundated with a specific company's ads, you can choose to hide them. Go to www.facebook.com/adpreferences/advertisers. There you will find a list of the advertisers you have seen most recently, and you can click on the "Hide Ads" button next to any offenders.

See fewer ads about specific topics (Not part of Privacy Checkup)

While you can't choose to see fewer ads overall, you can choose to see fewer ads in specific categories. Go to www.facebook.com/adpreferences/ad_topics to see the list of "Ad topics based on your activity on Meta Technologies." If you don't want to see ads based on one of the topics, click on the topic and select "Show less ads about this topic." If there are ads in the "Ad topics we show less of" that you wouldn't mind seeing, click on the topic and select "No preference."

Turn off personalized ads based on your activities off Facebook (Not part of Privacy Checkup)

You can choose to prevent Facebook from using data from its partners to show personalized ads. Go to www.facebook.com/adpreferences/ad_settings and click on "Data about your activity from partners." There, you can toggle off "Use Data from Partners."

However, this won't stop the off-Facebook tracking. If you want to stop sharing your off-Facebook browsing activity with Facebook, go to www.facebook.com/off_facebook_activity and click on "Disconnect future activity." This clears your previous off-Facebook activity and stops Facebook from connecting your activity to your account going forward.

Choose the profile information to share with marketers

Here, you can choose whether to share your marital status, employer, job title, and level of education with advertisers. This doesn't remove the information from your Facebook profile; it just impacts the ads you see.

You can also go directly to www.facebook.com/adpreferences/ad_settings and clicking on "Categories used to reach you." There you can toggle off any data you don't want to share.

Choose which interests to share with marketers (Not part of Privacy Checkup)

In addition to basic profile information, Facebook uses other information you've shared with it to serve you ads. You can remove interest categories, by going to www.facebook.com/adpreferences/ad_settings and click on "Categories used to reach you." Here, you can click on "Other categories." If you have other demographic or behavioral categories in your Ad Preferences, you can click on the "Remove" button next to any categories you don't want used to target ads to you.

Choose which advertisers can use their own audience list to target you with ads (Not part of Privacy Checkup)

Some companies have lists of people that they want to reach with their ads. Facebook allows companies to target ads based on these lists, or even exclude you from seeing ads (for example, the DNC may want to exclude their ads from people on the RNC list). You can choose not to be shown ads using a list, as well as not be excluded from seeing ads. Go to www.facebook.com/adpreferences/ad_settings and click on "Audience-based advertising." There, you will see a list of all of the companies that have you on their audience list. Click on a company, and you can find out why you were included in the advertiser's audience. Click on the arrow next to the reason, and you can choose whether the company's list can be used to either include or exclude you from seeing ads.

Choose whether you are shown ads off Facebook based on your interests (Not part of Privacy Checkup)

Facebook serves a lot of advertising on websites and through apps off of Facebook. You can turn off personalized ads for those sites and apps, by going to www.facebook.com/adpreferences/ad_settings and clicking on Ads Shown off of Facebook. There, you can toggle off personalized ads.

Choose whether your interactions with a company show up in ads

Have you ever liked or followed a company, made a comment, shared a company's Page, checked into an event held by a company, made a recommendation, or joined a Facebook event held by a company? Facebook can broadcast your action as an advertisement to all your friends.

If you don't like this type of inadvertent endorsement, you can limit who can see these social interactions alongside ads to "Only me."

You can also go directly to www.facebook.com/adpreferences/ad_settings and click on "Social interactions." In the popup, you can select "Only me" or "Friends."

That covers your privacy setting options on Facebook. If you want to dig in even further, Facebook has a page explaining the basics of Facebook privacy tools as well as Facebook's latest data policies.
