The fastest way to log out depends on what device you're using

On a computer, click the downward arrow in the top right corner of Facebook, then select "Log out" from the menu that appears. On a phone or tablet, open the Facebook app, tap the three horizontal lines (called a menu icon) at the bottom right, scroll down to "Log out", and tap it. If you're using Facebook in a web browser on your phone instead of the app, use the same computer steps above — the menu location is identical.

The logout button is always in the account menu, never buried in settings. Once you click or tap it, you are when ready signed out. Facebook will ask you to log back in the next time you visit the site or open the app.

If you cannot find the menu icon or the logout option, your browser or app may need an update. Check your device's app store or your browser's update settings, install any waiting updates, and try again.

Key Takeaways

  • On a computer, click the arrow in the top right corner and select "Log out" from the dropdown menu.
  • On the Facebook app for phones and tablets, tap the three horizontal lines at the bottom right, scroll to "Log out", and tap it.
  • Logging out on one device does not log you out on other devices — you must log out separately on each one.
  • If you want to stay logged out, close the app completely after logging out rather than just switching to another app.

Logging out on a computer or laptop

Open Facebook in any web browser and look at the top right corner of the page. You will see a small downward-pointing arrow or a circle with your profile picture. Click it. A menu will drop down with several options, including "Log out" near the bottom. Click "Log out" and the page will refresh — you are now signed out.

If you see a question mark icon instead of an arrow or picture, your browser may not have loaded the page fully. Wait a few seconds and refresh the page by pressing F5 on your keyboard or clicking the refresh button in your browser's address bar.

Logging out on the Facebook app for iPhone or Android

Open the Facebook app and look at the bottom of the screen. You will see five icons in a row. Tap the three horizontal lines on the far right (this is the menu icon). The screen will show a list of options. Scroll down past "Settings & Privacy" until you see "Log out". Tap it. The app will close and return you to the login screen.

On some older versions of the app, the menu icon may be in a different location. If you cannot find the three horizontal lines at the bottom, update the Facebook app from your device's app store and try again.

Logging out on Facebook in a mobile web browser

If you are using Facebook through Safari, Chrome, or another browser on your phone instead of the app, follow the same steps as a computer. Tap the arrow or profile picture in the top right corner, then tap "Log out" from the menu. The browser will sign you out and may return you to the Facebook login page.

Some phones display the top menu differently depending on whether you are scrolled to the top of the page. If you cannot see the arrow or picture, scroll to the very top of the Facebook page first.

What happens after you log out

Once you log out, Facebook will not show your activity to other users, and no one can post on your behalf. Your account remains active — nothing is deleted. The next time you or anyone else tries to access your account, Facebook will ask for your email address and password.

If you log out on your phone but stay logged in on your computer, you remain signed in on the computer. Logging out on one device does not sign you out everywhere. You must log out separately on each device you use.

Staying logged out if you share a device

If you share a computer or phone with someone else, logging out is important but not always enough. After you log out, close the browser completely or close the Facebook app entirely. Do not just switch to another app or browser tab — if you leave the browser open, someone else can click the back button and return to your account.

If you use a shared computer, you can also ask the device owner to enable a guest account or private browsing mode. In private browsing (called Incognito in Chrome, Private in Safari), Facebook will not stay logged in after you close the browser, even if you forget to log out manually.

If you cannot log out or the button does not appear

First, check that you are actually logged in. If you see a login screen with fields for email and password, you are already logged out. If you see your news feed or profile, you are logged in.

If you are logged in but cannot find the logout button, your app or browser may be outdated. On a phone, open your app store (Google Play on Android, App Store on iPhone), search for Facebook, and tap "Update" if it appears. On a computer, check your browser's menu for updates — most browsers update automatically, but you may need to restart them for the update to take effect.

If you have updated and still cannot log out, try logging out in a different browser or on a different device. This will tell you whether the problem is with your device or with your account. If the problem persists everywhere, you may need to change your password or contact Facebook's support through the Help Center in your account menu.

Frequently Asked Questions

Does logging out delete my Facebook account or my messages?

No. Logging out only signs you out of your account. Your profile, messages, photos, and all other information remain on Facebook's servers. Your account is still active — you can log back in anytime with your email and password.

If I log out on my phone, will I be logged out on my computer too?

No. Each device is separate. You must log out on your computer, your phone, your tablet, and any other device you use. Logging out on one does not affect the others.

What if someone else logs into my account after I log out?

They would need your email address and password. If you are concerned someone has your password, change it when ready by going to Settings & Privacy, then Settings, then Security and Login. You can also see a list of devices currently logged into your account on that same page.

Can I log out of Facebook without closing the app?

Yes. After you tap "Log out" in the app menu, the app will sign you out and show the login screen. You do not need to close or delete the app. The next time you open it, you will see the login screen instead of your news feed.

Is there a way to log out of Facebook on all devices at once?

Not through the logout button. However, if you change your password, Facebook will automatically log you out of all devices except the one you are currently using. Go to Settings & Privacy, then Settings, then Security and Login, then "Change Password" to do this.
