Single Sign-On (SSO)

An access solution that lets users log in once and gain access to multiple systems or applications without separate logins for each. With SSO, one set of credentials (often entered once at the start of the day) authenticates the user for all authorized apps.

‍

For example, an employee might use SSO to access their email, file storage, and CRM system via one central login portal. This is convenient for users (fewer passwords to juggle) and can be more secure for the organization - it allows centralized control over accounts and ensures that when a user leaves, disabling one account cuts off access everywhere.

For a small business, SSO can simplify user management and reduce password fatigue, which in turn cuts down on risky habits like password reuse.
