- Open Security & sessions and choose Set up authenticator. Enter your current password.
- Scan the QR code with your authenticator app, or enter the setup key manually. Keep the key private.
- Enter the current six-digit code to activate protection. Save the recovery codes somewhere safe; they are shown once.
- Future password sign-ins require an authenticator or recovery code. A code cannot be reused. Wait for the next code if necessary and ensure your device time is automatic. Existing passkeys remain a secure alternative.
