Several company users are frequently forgetting passwords for their mobile devices and applications. Which of the following should the systems administrator do to reduce the number of help desk tickets submitted?
A. Implement single sign-on.
B. Enable multifactor authentication.
C. Configure biometric authentication.
D. Remove complex password requirements.

The single sign-on (SSO), is the working method by which workers gain access to different business applications through a registration procedure. For example, when you log in from your computer, you connect directly to all the computer software. There are two ways of single sign-on:

Basic SSO
Federated SSO

With the basic SSO, the password is saved in a "vault", a type of virtual security. This storage usually occurs in the cloud. Then, that vault password is retrieved for all applications that must log in later.

Federated SSO is a more advanced form of single sign-on. In this case, the password data is not stored or transmitted. First, they become tokens. Therefore, another code is created and the original password is not known by any other system.
