Your security screens list everyone you have blocked and every device signed in to your account. You can block a user, unblock them, and end any session you do not recognise.
Both are in your security screens.
Blocking someone
Search for the account and block it. Blocked users are listed on the same screen and you can unblock any of them.
Blocking is about who can reach you. If someone is breaking the rules rather than simply bothering you, report them as well — blocking stops them reaching you and tells us nothing.
Devices signed in
The sessions list shows where your account is signed in. Anything you do not recognise can be ended from there.
If you think somebody else has been in your account
Do all three, in this order:
- Change your password. That signs every other device out on its own.
- Turn on two-factor — see two-factor and passkeys.
- Tell us, so we can check whether anything was changed.
