Salesforce Certified Identity and Access Management Practice

Single sign-on (SSO) in Salesforce operates by allowing users to log in once and access multiple applications seamlessly. This functionality simplifies the login process, as it eliminates the need for users to remember and enter separate credentials for each application they wish to use.

When a user authenticates through the SSO, a secure token or assertion is generated, which the user can then present to various applications that are integrated within the SSO framework. This token is verified by the respective applications, granting access without prompting the user to re-enter their credentials each time.

Implementing SSO greatly enhances user experience, improves productivity, and bolsters security by reducing the number of passwords users must manage, thereby decreasing the likelihood of poor password practices. Overall, SSO streamlines access management across systems, making it an essential capability in modern enterprise environments.

The other responses present aspects that do not accurately represent the core function of SSO. They discuss requirements for multiple credentials, temporary tokens for each session, and geographical verification, which are not defining characteristics of SSO in Salesforce.
