FIDO2 passwordless solutions drive significant enterprise and customer value as well as enhanced security. Yet many FIDO2 passwordless solutions cannot deliver user certainty, since they do not verify the identity of the true account owner during device registration. AuthID will review a best-practice approach to device-based authentication that incorporates seamless, biometric identity verification that establishes a trusted identity during FIDO2 device registration. This practice allows companies that implement passwordless login to establish a digital chain of trust between biometrically verified individuals, their accounts, and their devices. The presentation will put into context a case study of an international bank.
