- 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.

- Option 'a' states about the username which is used in the first authentication.

Explanation:
Assuming your employment is terminated, notifying your employer of all accounts you have access to, and requesting that they change all passwords before you leave is a behavior that would not harm a company.

Some mischievous and malicious employees would rather not tell so they can still have an unauthorized access to the company's account and perpetrate various level of evil.
Hence, it is a good global practice to have a company's login credentials updated whenever an employee's employment is terminated.
