COMPUTER FUNDAMENTALS

Detailed explanation-1: -Username and password authentication is a method of verifying the identity of a user accessing a digital system. The user provides a unique identifier, called a username, and a secret, called a password, to gain access. The system then compares this information with its stored database to verify the user’s identity.

Detailed explanation-2: -In authentication, the user or computer has to prove its identity to the server or client. Usually, authentication by a server entails the use of a user name and password. Other ways to authenticate can be through cards, retina scans, voice recognition, and fingerprints.

Detailed explanation-3: -In SSL/TLS, clients and servers use digital certificates to authenticate each other before connecting. Client certificates and server certificates are exchanged to verify each party’s identity in a process known as mutual identification. The server certificate is a small data file saved on the web server.

Detailed explanation-4: -What is Password-Based Authentication? Password-Based Authentication is the process of gaining access to resources to which one is entitled with the help of a set of credentials containing a username and password. This is a rampantly used method known for process simplicity and low cost.
