Answer:
Option d is the correct answer for the above question.
Explanation:
- Authentication is a process that enables the user to enter the system. This process helps to secure the data. It is because with the help of this only valid users can enter the system. In this process, the system asks some unique information from the user which can only be known to the valid user.
- Some systems put two types of authentications one is some information about the valid user and the other is a fingerprint scan that takes the data of the user finger and matches with their user name and password. If it matches then only he can enter into the system.
- The above question asks about the mechanism which is used for multifactor authentication. This authentication is known as a fingerprint scan. So the option D is the correct answer while the other is not because:-
- Option 'a' states about the username which is used in the first authentication.
- Option b states about pin which can be used in the place of username.
- Option c states about the security question which is used when the user forgets the password.
A fingerprint scan provides an authentication mechanism that would be appropriate for pairing with a password to achieve multifactor authentication (Option D).
- A fingerprint scanner is a biometric security system used by different institutions and devices such as, for example, the policy or smartphones.
- This device (fingerprint scanner) captures the patterns of ridges and valleys on a finger, which are highly specific and vary between different persons.
- Moreover, multifactor authentication refers to the technologies that use multiple procedures of authentication from independent categories.
In conclusion, a fingerprint scan provides an authentication mechanism that would be appropriate for pairing with a password to achieve multifactor authentication (Option D).
