The process of identifying an authorized user on a computer is typically managed by the computer's operating system. When a user logs into a computer, they are usually required to provide some form of identification, such as a username and password, in order to access the system. The operating system then verifies this information and grants the user access to the computer if the identification is correct.
In addition to usernames and passwords, other forms of identification may be used to verify a user's identity, such as biometric authentication (e.g. fingerprint or facial recognition) or smart cards. These methods can provide an additional layer of security to help prevent unauthorized access to a computer system.
Overall, the identification of authorized users on a computer is an important aspect of computer security, and various technologies and techniques are used to ensure that only authorized users are able to access sensitive information and perform actions on the system.
