What is what does it mean when facebook says session expired?

A "session expired" message on Facebook (or any website) means that your current login session has ended. This essentially means the website no longer recognizes you as being logged in, even if you were just using it moments ago.

Here's a breakdown of what that entails:

  • Timeout: Facebook (and other websites) sets a time limit for how long a session can last. If you're inactive for a certain period, the session will automatically expire. This is a security measure to prevent unauthorized access if you leave your computer unattended.

  • Security Reasons: If Facebook detects suspicious activity on your account (like logging in from a new location), it might expire your session to protect your account.

  • Logging Out from another device: Manually logging out from another device will also end the session there, potentially affecting any other devices you are logged in on.

  • Cookie Issues: Cookies are small files that websites use to remember your login information. If these cookies are corrupted, deleted, or blocked, your session can expire.

  • Browser Settings: Certain browser settings or extensions might interfere with Facebook's ability to maintain your session.

When you see this message, you'll need to re-login with your email/phone number and password to start a new session.
