Activating two-factor authentication

Add a second factor — an authenticator app, security key, or passkey — to protect your account.

Two-factor authentication (2FA) protects your sign-in even if your password is exposed. Because your account controls domains and DNS, enabling it is the single most important security step you can take.

Set it up

Go to Settings → Security → Two-factor authentication.
Scan the QR code with an authenticator app, or register a hardware security key or passkey.
Save the one-time backup codes somewhere safe in case you lose your device.

Passkeys are even better

A passkey uses your device biometrics or a security key and is resistant to phishing, because there is no code an attacker can trick you into typing. Add one under the same Security page — passwords remain as a fallback while you transition.

Store your backup codes offline. They are the way back in if you lose access to your second factor.
