Authentication in Distributed System
A user’s identity (or that of a service, process, or server) can be established and verified by authentication. Following successful authentication, a procedure can determine what kind of access is allowed and whether to grant access to the service or its resources. It’s known as authorization.
The three elements of authentication are a personal identifier (PIN or password), a personal identifier (key or card), and a personal identifier (biometric).
The user registered in the distributed system during the authentication process. When a user logs in using a PIN, password, key, card, or biometric, the system compares their credentials with the information stored in the database; if they match, access is granted to the authorized user.
It improves security and is useful to the user.
