Logged in as someone else...

Hello,

Some minutes ago I logged in as someone else. I got access to all her information.

This shouldn't be possible! This is a serious security problem!

If you where logged in as someone else, either:
- You logged in using their details, or they have signed in on your device last and its remembered their details.
- Your Facebook account has become tied to someone elses account (which is common sometimes you share devices with people), so when you log in with your Facebook details you get their account rather than your own.

If you log out and back in again is it fixed?

I am the only user that uses this laptop...
But for now the problem is solved.
