Google Authenticator now supported for two-factor authentication
FastMail has long supported various methods of two-factor authentication for additional account security, from generated one-time-passwords, to SMS, to Yubikey. Today we've added another method to our stable - the Google Authenticator method, otherwise known as Time-based One Time Passwords (RFC 6238). With this you can use your iOS, Android or almost any other mobile device as your second factor when authenticating, increasing the security on your account without requiring you to carry an additional object around with you.
A Google Authenticator alternative login can be configured in the Alternate Logins section of your account settings screen. If you're using the official Google clients, then you can use its support for QR codes to make setup super-easy. You can however choose to use any number of other clients that support this authentication mechanism; all will work with our implementation.
