Answer:
The correct answer is A. Implement single sign-on.
Explanation:
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:
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.
