How to Log Off of Facebook: Every Device and Situation Covered
Logging off of Facebook sounds simple — and usually it is. But depending on whether you're on a phone, a shared computer, or trying to sign out of a device you no longer have in your hands, the process works differently. Here's a clear breakdown of every method, so you know exactly what to do in your situation.
Why Logging Out of Facebook Actually Matters
Staying logged into Facebook on a personal device you own and control is generally fine. But there are real reasons to log out:
- You're using a shared, public, or borrowed device
- You want to switch between Facebook accounts
- You're troubleshooting an app glitch
- You want to limit background data usage or notifications
- You're handing a device to someone else temporarily
The method you use depends entirely on the device and whether you have physical access to it.
How to Log Out of Facebook on a Desktop or Laptop Browser 💻
This is the most straightforward version:
- Go to facebook.com and make sure you're logged in
- Click the down-arrow icon (or your profile picture) in the top-right corner of the screen
- Scroll to the bottom of the dropdown menu
- Click "Log Out"
You'll be immediately signed out and returned to the Facebook login screen. This works in Chrome, Firefox, Safari, Edge, and any other standard browser.
Important: Logging out in one browser does not log you out in another. If you're signed in on Chrome and Firefox simultaneously, you'd need to log out of each separately.
How to Log Out of the Facebook App on iPhone or Android 📱
The mobile app buries the logout option a little deeper than most people expect.
On iPhone (iOS):
- Tap the three horizontal lines (hamburger menu) in the bottom-right corner
- Scroll all the way down
- Tap "Log Out"
On Android:
- Tap the three horizontal lines in the top-right corner
- Scroll down to the bottom of the menu
- Tap "Log Out"
On both platforms, Facebook may ask if you want to save your login information for next time. If you're on a shared phone, tap "Not Now" or "Don't Save."
How to Log Out of Facebook Remotely (Devices You Don't Have With You)
This is where things get more useful. If you left yourself logged in on a friend's computer, an old phone, or a device you've since sold or lost, Facebook lets you sign out remotely.
Here's how to do it from any device where you are currently logged in:
- Go to Settings & Privacy → Settings
- Find "Security and Login" (desktop) or "Password and Security" (mobile app)
- Look for the section called "Where You're Logged In"
- You'll see a list of all active sessions — device type, browser, approximate location, and time
- Click or tap the three dots next to any session
- Select "Log Out" for that specific session, or choose "Log Out of All Sessions" to clear everything at once
This is particularly useful if you notice any unfamiliar sessions in that list — devices or locations you don't recognize. Logging those out immediately is a good security habit.
Logging Out vs. Deactivating vs. Deleting: What's the Difference?
These are three very different actions that people sometimes confuse:
| Action | What It Does | Reversible? |
|---|---|---|
| Log Out | Ends your session on a device; account stays active | Yes, instantly |
| Deactivate | Hides your profile and content temporarily | Yes, log back in to reactivate |
| Delete | Permanently removes your account and data | Limited window to cancel |
Logging out is purely a session-level action — nothing about your account, posts, friends, or data changes. You're simply ending the authenticated connection between that device and your Facebook account.
When Logging Out Doesn't Work as Expected
A few situations where logout behaves differently than you might expect:
Facebook Messenger: Logging out of the main Facebook app does not automatically log you out of Messenger if it's installed separately. You'd need to log out of Messenger independently through its own menu.
Saved passwords in your browser: If your browser has saved your Facebook credentials and is set to auto-fill, you may find yourself logged back in almost immediately after logging out. Clearing saved passwords for facebook.com in your browser settings fixes this.
Remembered login on mobile: If you tapped "Save Password" or "Remember Me" at some point, the app may re-authenticate you quickly after logout. Removing the saved account from the login screen prevents this.
Third-party apps connected to Facebook: Logging out of Facebook doesn't revoke access for apps that use "Login with Facebook." Those connections are managed separately under Settings → Apps and Websites.
The Variable That Changes Everything
How straightforward your logout experience is depends heavily on your setup. Someone logging off a personal laptop they use daily has a one-click process. Someone trying to remotely sign out of a device they no longer own needs to navigate security settings and may also want to change their password to invalidate existing sessions entirely.
The number of devices you're logged in across, whether you share devices with others, and whether you've connected external apps through Facebook login all shape what "logging out" needs to mean for you specifically — and whether a single logout action is actually enough.
