Finch, a security professional, was instructed to strengthen the security at the entrance.

The combination of authentication mechanisms that is implemented in the above scenario is biometric and password authentication. Biometric authentication is a type of authentication that uses an inherent factor, such as a retina scan, to verify the identity of the user. Password authentication is a type of authentication that uses a knowledge factor, such as a six-digit code, to verify the identity of the user. By combining biometric and password authentication, Finch has implemented a two-factor authentication (2FA) system that requires the user to provide two different types of authentication factors to gain access to the office. 2FA is a more secure way of authentication than using a single factor, as it reduces the risk of unauthorized access due to stolen or compromised credentials.Biometric and password authentication is a common 2FA method that is used in many applications, such as banking, e-commerce, or health care123.References:
