Settings & Security

Change your sign-in email on the Your details tab and your password on the Security tab, and what to do if you have forgotten your password.

Every sign-in with a password asks for a second step. Switch from emailed codes to an authenticator app, and keep recovery codes in case you lose your phone.

Add a passkey in Settings, choose how it checks it is you, and turn off password sign-in if you want to rely on it alone.

Delete your account yourself from Settings. What is removed, what ends with it, and the cases where you have to take another step first.
