is a term that denotes a user’s capability to authenticate once to access the network and then have automatic authentication on different applications and devices afterward.

Single sign on is a term which represents a user’s capability to authenticate once to access the network and then have automatic authentication on different applications and devices afterward.

Explanation:

Authentication can be achieved through a method called single sign on (SSO).

By using this method, a user can get access to different applications with a single set of login credentials therefore, simplifying the authentication process.

Benefit:

The main benefit of SSO is time saving.

For example, if a user has 5 different login credentials for 5 different applications then it will be very time consuming and also there will be more chances of error which means more loss of time.

Challenge:

The main challenge to SSO is is security risk.

For example, if the login credentials are compromised then the hacker will have access to all the connected applications too. It is usually advised to add two factor authentication for improved security.
