Push / SMS, QR or time-based passcodes - the choice is yours.
Time-based passcodes deliver an in-app code linked to the user's account. Each passcode is valid for 60 seconds, after which a new code is displayed.
Push / SMS passcode
Push / SMS passcodes deliver a custom one-time passcode direct to a user's mobile device. Each unique passcode expires after 60 seconds.
QR code authentication
QR authentication requires the user to scan a QR code to generate a one-time passcode. Each QR code is unique and paired with a user's identity.
