What is Single sign-on (SSO)?
Single sign-on lets people use one login, such as their Microsoft or Google work account, to access many applications. The identity provider confirms who they are, so each app does not need its own password.
Why it matters for your business
SSO improves security and makes life easier for users and IT, because access is granted and removed in one place.
Employees open the company's custom portal and are signed in automatically with their Microsoft 365 account; leavers lose access the moment their account is disabled.
