How To Sign Out and Log Off Facebook Messenger Mobile App

Facebook Messenger is a popular messaging app used by over a billion people worldwide. It allows users to easily communicate with friends and family through text, voice, video calls, and more.

While the app makes staying connected incredibly convenient, there may be times when you want to sign out of your account on your mobile device for privacy or other reasons. However, unlike most apps, Facebook Messenger does not have a straightforward “log out” option.

In this comprehensive guide, I will walk you through the step-by-step process to sign out and log off Facebook Messenger on both Android and iOS devices.

Why Log Out of Facebook Messenger?

Here are some common reasons you may want to log out of the Facebook Messenger app on your phone:

  • Privacy: Logging out prevents others from accessing your messages if they get ahold of your device. It also gives you peace of mind that your conversations stay private.
  • Security: Signing out adds an extra layer of protection in case your phone gets lost or stolen. It ensures no one can access your FB account from that device.
  • Switch Accounts: Logging out allows you to easily switch between different Facebook accounts on the Messenger app.
  • Temporary Break: Sometimes you may just want a break from the constant notifications. Logging out lets you take a vacation while still keeping the app.

How to Log Out on Android

Logging out of Facebook Messenger on an Android device takes a few more steps than other apps since there is no standard “log out” option.

Here is the process:

  1. Open the Settings app on your Android device.
  2. Tap on Apps & notifications.
  3. Tap See all apps.
  4. Scroll down and tap the Messenger app.
  5. Tap Storage & cache.
  6. Tap Clear storage and confirm by tapping OK.

This will sign you out by clearing all locally stored Messenger data on your device. When you open the app again, it will prompt you to log back in with your Facebook credentials.

Alternative Method via Facebook App

If you have the Facebook app installed, you can alternatively log out of Messenger using these steps:

  1. Open the Facebook app and tap the ≡ menu icon.
  2. Go to Settings & privacy > Settings.
  3. Tap Security and login.
  4. Under Where you’re logged in, tap the ⋮ next to Messenger and select Log out.

How to Log Out on iPhone

The process is a bit different on iOS. Here is how to sign out of Facebook Messenger on an iPhone or iPad:

  1. Open the Facebook app (not Messenger).
  2. Tap the ≡ menu icon and go to Settings & Privacy > Settings.
  3. Scroll down and tap Security and Login.
  4. Under Where You’re Logged In, find the entry with Messenger listed below your device name.
  5. Tap the ⋮ next to your device and select Log Out.

This will sign you out of Messenger across all platforms. You’ll have to log back in next time you open the Messenger app.

Logging Back In After Signing Out

After signing out using the steps above, opening the Messenger app will prompt you to log back in using your Facebook credentials.

Simply enter your Facebook email and password when asked.

If you checked “Keep me logged in” when previously logging in, your username may automatically populate – just enter your password to log back in.

Once logged back in, all your previous messages and Messenger data will reappear as they were before signing out.

Tips for Managing Your Messenger Account

  • Enable two-factor authentication on your Facebook account for an extra layer of login security that applies to Messenger as well.
  • Use Messenger’s Secret Conversations feature when you want end-to-end encryption for your chats. This prevents anyone besides you and the recipient from reading messages.
  • Limit ad tracking for more privacy by going to your Facebook Ads Preferences. This prevents your Messenger activity from being used to target you with ads.
  • Temporarily deactivate your Facebook account if you want to take an extended break from Messenger and social media. This pauses your account until you reactive it by logging back in.


While Facebook Messenger does not have a native “log out” function, with the steps above you can easily sign out on both iPhone and Android devices.

Logging out is useful for privacy, security, switching accounts, and just taking a break from Messenger notifications. Keep this guide handy any time you need to sign out!
