Reality (and multiple data breaches) shows that passwords, ID numbers or PINs are not safe, and definitely not sufficient as a standalone authentication factor. No matter how complex we make our passwords, there is still a need for additional layers of security. That is what makes biometrics so popular. From accessing our mobile devices, through opening our office door, to accessing our bank account or talking to a contact center agent, we see more day-to-day applications for biometrics as a means of authentication. Biometric-based authentication is more secure than any other method and ties an identity to a specific individual rather than a password or a code that could be used by anyone.
