Use the same sign-in method
If you originally signed up with Google, Apple, or an email sign-in link, use that same method again. Email sign-in sends a sign-in link; it does not use a classic password reset flow.
Other common cases
If you used Sign in with Apple, your account email may be an Apple private relay address.
If your account was self-closed, email sign-in can be blocked until support reviews the case.
If you were charged but cannot reach the account, start on the support page.
