Microsoft Entra provides Single Sign-On (SSO) functionality. This means that you can access multiple independent software applications with a single set of credentials. With SSO, a user doesn’t have to log in for each application individually. SSO allows users to access all the necessary applications without having to authenticate with different credentials. Microsoft Entra ID offers several SSO options, including password-based SSO, link-based SSO, and federation-based SSO. Federation-based SSO is SSO’s richest mode and is supported for SAML 2.0, WS-Federation, or OpenID Connect applications.

Microsoft Entra Connect provides seamless SSO functionality for users who are signed in on their corporate devices connected to your corporate network. When this feature is enabled, users don’t need to enter their passwords to sign in to Microsoft Entra ID, and they usually don’t even need to enter their usernames.
