How do I sign out of all other devices?

There's no explicit "log out everywhere" button because there's no need for one. We use a single-active-session model: signing in on a new device or browser automatically terminates the previous session.

If you want to kick someone off your account:

1. Sign in fresh from your trusted device. Any other session is instantly terminated.
2. Change your password so the same credentials can't be used to sign in again.
3. Enable 2FA if you haven't already — a leaked password should not be enough to sign in.
4. Check Active Sessions for anything unfamiliar.
