Registering a security key for your account is available after enabling 2FA with a TOTP application. Most browsers can use the fingerprint reader, facial recognition, or password/PIN on your device as a security key as well. On most devices and browsers, you can use a physical security key over USB or NFC. For more information, see " WebAuthn" and " Can I Use." WebAuthn is the successor to U2F and works in all modern browsers. The technology that enables authentication with a security key is called WebAuthn. In case of problems, such as a forgotten password or typo in your email address, you can use recovery codes to access your account and correct the problem.Ĭonfiguring two-factor authentication using a security keyĪfter you configure 2FA, using a time-based one-time password (TOTP) mobile app, you can add a security key, like a fingerprint reader or Windows Hello.
