Authentication based on something the user has, combined with a PIN, is known as two-factor authentication (2FA). This method requires a user to provide a physical object, such as a security token or a smartphone app, along with a personal identification number (PIN) to verify their identity. This adds an additional layer of security, as even if someone obtains the PIN, they would still need the physical device to gain access. Such a system helps protect against unauthorized access and enhances overall security.
An ID card portrays authentication based upon something the user has.
Not always. Authentication is based upon one or more of the following:Something the user knows (such as a PIN).Something the user has (such as an ID card).Something the user is (such as a fingerprint).
Yes. Any biometric reading, such as a fingerprint, retina scan or DNA sample portrays authentication based upon something the user is.
You cannot portray identification upon something unknown. It must be something known only to the user, or be something the user is (such as a fingerprint, retina scan or DNA sample) or something the user has (such as an ID card).

1. Fingerprint.
Two-factor authentication uses something a user has in conjunction with something a user knows.
An authentication system that uses something a user has in conjunction with something a user knows is called:
An authentication system that uses something a user has in conjunction with something a user knows is called:
Three common ways to authenticate someone are: Knowledge-based authentication: This involves something the user knows, such as a password or PIN. Possession-based authentication: This requires something the user has, like a security token, smart card, or mobile device for SMS verification. Biometric authentication: This uses unique biological traits, such as fingerprints, facial recognition, or iris scans, to verify a person's identity.
No. A biometric identification, such as fingerprint, retina scan or DNA sample portrays something that the user is.Authentication is achieved in one of three ways:something the user is (a biometric reading)something a user has (such as an ID card)or something the user knows (such as a PIN)For improved security, the user may be required to present two such authentications, such as an ID card and PIN. Or, preferably, all three, such as an ID card, PIN and retina scan.
