Received login warning from unknown device

Facebook sends you a notification when someone logs into your account from an unfamiliar device or location. If you don't take action, it's likely someone is trying to gain unauthorized access. → Action: Change your password immediately and check your login history under “Security and Login.”

Strange posts, messages or friend requests appear

If you see content you didn’t create—like promotional posts, strange messages to friends, or unusual friend requests—it’s a sign your account has been hijacked. → Action: Change your password and notify your friends to avoid being scammed.

Cannot log into account

You were unexpectedly logged out and can't log back in with your old password. Facebook may notify you that your password has been changed or that your account is locked due to a suspected intrusion. → Action: Use the “Forgot Password” feature to recover your account, then change your password to a stronger one.

Receive email confirmation of changes you didn't request

If you receive an email from Facebook confirming a password, email, or phone number change that you did not make, it is a clear sign that your account has been compromised. → Action : Go to Facebook immediately to check and change your password, enable two-factor authentication.

Sharing the same password with multiple accounts

If you use the same password for Facebook and other platforms (email, banking, shopping…), the risk of being hacked is very high – especially if one of those services has a data leak. → Action: Change to a separate password for Facebook, avoid repeating it on other platforms.

Suspect someone knows your password

Have you shared your password with someone, or suspect someone is tracking your Facebook activity? Don't wait. → Action: Change your password now and enable two-factor authentication for added security.

How to protect your Facebook account effectively:

  • Use a strong password: at least 10 characters, including uppercase, lowercase, numbers, and special characters.
  • Enable two-factor authentication (2FA) to prevent unauthorized access.
  • Check your login history regularly.
  • Do not click on strange links or log in through unofficial websites.
  • Change your password periodically, especially after any unusual signs appear.
