Facebook keeps moving that logout button around, so older tutorials look wrong now. Here is where to find it step by step.
On the Facebook mobile app
(Android and iOS are almost the same now):
- Open the Facebook app.
- Look at the bottom or top right corner.
You should see three horizontal lines. People call it the “menu” icon. - Tap that menu icon.
- Scroll all the way down to the bottom of the menu.
- You should see “Log out” in plain text at the bottom.
- Tap “Log out”.
- If it asks to “Remember this device” or similar, choose no if the device is shared.
If you do not see “Log out” at the bottom:
- Check the profile picture circle in the top right after you open the menu.
- Tap your profile picture.
- There should be a “Log out” option in that small dropdown.
On the Facebook website on desktop or laptop:
- Go to facebook.com and make sure you are logged in.
- Look at the very top right.
- You should see a small circle with your profile picture.
- Click that profile picture circle.
- A small menu opens.
- “Log out” sits as the last option in that menu.
- Click “Log out”.
If the browser or app looks different:
- Try updating the Facebook app from the App Store or Google Play.
- Clear browser cache if you use a desktop browser.
- Try another browser like Chrome, Firefox, or Edge.
- Check if you are on “m.facebook.com” on mobile browser. On that version, the menu icon with three lines sits at the top right, and logout sits at the bottom of that menu.
To be extra safe on a shared device:
- After logging out in the app, also remove the account.
• In the login screen you might see your profile “bubble”. Tap the three dots on it, choose “Remove account from this device”. - On a browser, clear saved logins.
• Chrome: Settings → Autofill → Password Manager, remove any saved Facebook password for that device. - Use Facebook’s security checkup.
• Go to Settings & privacy → Settings → Security and login.
• Look for “Where you’re logged in”.
• Click “See more”.
• Click “Log out of all sessions”. This forces every device out, including phones, tablets, and old shared computers.
If “Log out” never shows up even after all that:
- Check if some content overlay covers the menu, like a popup or chat window. Close those.
- Try landscape mode on your phone. Sometimes UI glitches hide the bottom area.
- Reinstall the Facebook app. Remove it, then install again from the store, then log out after logging back in once.
You are right to worry on a shared device. Facebook often keeps people signed in by default, and auto-login with cookies and saved passwords is common. Logging out from “Where you’re logged in” and removing saved passwords handles that risk.
