+## Locked account after failed login
+To protect against brute-force password guessing, temporarily locks your account after 5 unsuccessful sign-in attempts.
+
+If this happens, you will receive an email with a link to restore your account.
+
+The account is locked for 5 minutes initially. However, if incorrect credentials are entered repeatedly after the account is restored, it will be locked for 1 hour.
