account settings got a security tab. you can now see every active session with its device, location, ip, and last-active time, and sign out individual sessions or every other device at once.
connected sign-in methods (google, apple, discord, x.com, plus email) are also listed there, so you can link extra providers or disconnect ones you don’t use, as long as you keep at least one method on the account.
two-factor authentication is next — authenticator app and sms support is coming soon so you can require a code on sign-in.
