Two-factor authentication
Protect your account with a TOTP authenticator app and a set of single-use recovery codes.
Enable two-factor authentication from account settings, scan the QR code with Google Authenticator, 1Password or any TOTP app, and confirm with a code. From then on, signing in asks for a second factor.
You are issued ten recovery codes at setup — store them somewhere safe. If you lose both your device and your codes, support can reset the factor for you.
