Where to find Facebook's privacy controls
Facebook's privacy settings live in two places: your account settings and individual post controls. The fastest route is to click your profile picture in the top right corner, then select Settings and privacy, then Settings. This opens your account dashboard. On the left side, you'll see a menu — click Privacy to reach the main controls that affect your whole profile.
The second place is on individual posts. When you create a post or look at an old one, you'll see a small icon showing who can see it — usually a globe, a group of people, or a lock. Click that icon to change who sees just that post, without changing your overall settings.
These two layers work together. Your account privacy settings are the default for new posts, but you can override them post by post. Understanding both is what gives you real control.
Key Takeaways
- Facebook's main privacy controls are in Settings and privacy > Settings > Privacy on the left menu, where you set defaults for who sees your posts and profile.
- You can change who sees individual posts by clicking the audience icon (globe, people, or lock) on each post, overriding your default settings.
- The three most common audience choices are Public (anyone on or off Facebook), Friends (only people you've added), and Only Me (just you).
- Your friends list, search visibility, and who can contact you are separate controls in the same Privacy menu and deserve their own attention.
- Facebook's default settings often favor sharing more widely than most people intend, so checking these controls when you first join or after a Facebook update is worth your time.
Controlling who sees your posts and profile
In the Privacy menu, the first setting is Who can see your posts? This is your default audience. The three main options are Public (anyone, including people not on Facebook), Friends (only people you've added as friends), and Only Me (just you). Most people choose Friends, but if you use Facebook for work or community organizing, Public might make sense. Only Me is useful if you want to post something for your own record without sharing it.
Below that is Who can see your friends list? This controls whether people can click on your profile and see everyone you're connected to. Many people set this to Friends or Only Me to avoid having their entire social network visible to strangers or acquaintances.
The third major control is Who can look you up using the email address or phone number you provided? If you set this to Friends, only people already connected to you can find you by searching your email or phone number. This is a real privacy gain if you want to limit how easily strangers can locate you.
Limiting who can contact you and tag you
Facebook lets people message you even if they're not your friends — by default, these messages land in a separate "Message Requests" folder rather than your main inbox, but they still arrive. In the Privacy menu, look for Who can send you friend requests? and Who can message you? If you set both to Friends, you'll hear only from people you've already connected with.
Tagging is another control worth checking. When someone tags you in a photo or post, it links to your profile and shows up on your timeline. In the Privacy menu, find Review tags people add to your posts before the tags appear on your timeline? Turning this on means you approve tags before they're visible, giving you a chance to untag yourself if you don't want to be associated with something.
There's also Who can see posts you're tagged in on your timeline? This is separate from whether the tag appears — it controls whether your friends see it when they visit your profile. You can set this to Friends, Only Me, or a custom list.
Adjusting search and discovery settings
Facebook has a separate section for search visibility. In Settings and privacy > Settings, click How people find and contact you. Here you'll find Do you want your profile to be searchable? If you turn this off, your profile won't appear when people search for your name on Facebook or in search engines.
You can also control whether your profile appears in search engines outside Facebook. The setting Allow search engines outside of Facebook to link to your profile affects whether Google, Bing, and other search engines can index your Facebook profile. Turning this off means your profile won't show up in a Google search, though Facebook's own search will still find you if you're searchable within Facebook.
These settings matter if you want to keep your Facebook presence separate from your public online identity, or if you prefer not to be easily discoverable by people you haven't connected with.
Controlling what apps and websites can see
Facebook lets third-party apps and websites access some of your information — your name, profile picture, email, and sometimes more. In Settings and privacy > Settings, click Apps and websites. You'll see two sections: Active (apps you've used recently) and Expired (apps you haven't used in a while).
Click any app to see what information it can access. You can remove access entirely by clicking Remove. If you want to limit what an app sees without removing it completely, click the app name to see what permissions it has — though Facebook doesn't always let you pick and choose individual permissions the way some other platforms do.
Many people don't realize how many apps they've connected to Facebook over the years. Reviewing this list and removing apps you no longer use is a straightforward way to reduce the number of companies that have your data.
Changing privacy after you've already posted
If you've posted something and want to change who can see it, you don't have to delete it. Click the three dots in the top right corner of the post, then select Edit the audience. This opens the same audience selector you see when creating a post — you can change it from Public to Friends, or to Only Me, or to a custom list of specific people.
This works for photos, videos, and text posts. It's useful if you realize you posted something more widely than you intended, or if your relationship with someone changes and you want to hide old posts from them.
One thing to know: changing a post's privacy after the fact doesn't erase it from people who already saw it. If someone screenshotted it or shared it, that copy is out of your control. But it does prevent new people from finding it going forward.
Understanding Facebook's default settings
When you first create a Facebook account, the default settings often allow more sharing than most people expect. Your posts default to Public or Friends depending on your account type, and your friends list is usually visible to everyone. Facebook doesn't hide these defaults — they're just not obvious unless you look for them.
After major Facebook updates, privacy settings sometimes reset or change. If you haven't checked your privacy controls in several months, it's worth revisiting them. Facebook announces changes in the Settings menu, but the announcements are easy to miss.
The reason to understand these defaults is simple: they're designed to maximize sharing, not privacy. That's not a secret or a scandal — it's how Facebook makes money, by showing your activity to as many people as possible so advertisers can reach you. Knowing that means you can make a conscious choice about what you're comfortable with, rather than accepting the default by accident.
Frequently Asked Questions
Can I make my profile private so only friends can see anything?
Yes. Set Who can see your posts? to Friends, set Who can see your friends list? to Friends or Only Me, and set Who can look you up using email or phone? to Friends. This prevents strangers from seeing your profile, posts, or social connections. People who aren't your friends still won't be able to message you if you set Who can message you? to Friends.
If I block someone, can they still see my old posts?
No. When you block someone, they can't see your profile, posts, or friends list — including posts they could see before you blocked them. However, if they were tagged in a photo with you before the block, they can still see that photo on their own profile. Blocking is one of Facebook's strongest privacy tools.
What does "custom" audience mean when I'm posting?
Custom lets you choose specific people or groups to see a post. You can type in individual names, or select a friend list you've created. This is useful if you want to share something with close friends but not your entire friend list, or with family but not coworkers.
Do privacy settings stop Facebook from collecting my data?
No. Privacy settings control who sees your posts and profile, but Facebook collects data about your activity regardless — what you click, what you search for, which ads you see, and which websites you visit outside Facebook. Privacy settings don't stop that collection. They only control who else can see what you share.
Why does Facebook keep changing my privacy settings?
Facebook updates its interface and sometimes resets settings as part of those updates. It's not usually intentional — it's a side effect of how the platform evolves. Checking your privacy settings after a major Facebook redesign is a good habit, because your preferences may have shifted to Facebook's defaults.
