Universal Authentication (also known as web authentication) is a method of authentication used on a computer network to validate a user’s identity. It is a single sign-on (SSO) technique which grants a user access to multiple available resources on the network, without needing to individually authenticate (enter the username and password) for each one.
It works by authenticating the user’s identity once, then granting them access to all the available resources in the network. It is usually accomplished through token-based authentication. The user is initially authenticated by entering a username and password, or another form of credentials. If the credentials are correct, the user is granted access to the resources.
Universal authentication is beneficial to both the user and the system. It is much simpler and quicker for the user, because they only need to remember one set of credentials, instead of separately entering credentials for each individual resource on the network. Furthermore, it prevents abuse and unauthorized access by only allowing those with valid credentials access to the network.
Universal authentication is widely used on web-based systems, such as websites, applications, and online services. It is also used on local network systems, such as in a business, school, or other institution, to allow for easy access to the many resources available.
Universal authentication is a powerful tool for computer security; however, it is important to remember that it is still vulnerable to unauthorized access. In order to ensure the safety and security of the system, it is important to implement additional layers of defense, such as strong encryption and secure protocols. This will help keep the system safe and prevent any unauthorized access.
