Single Sign-On (SSO) is supported by intelliHR if you are using a SAML 2.0 based identity provider. SSO means that one set of login credentials can be used to access multiple applications. This type of authentication can assist employees who have a growing number of user accounts. If enabled, SSO will mean that when attempting to log into intelliHR, users will get redirected to their own identity provider (such as Active Directory, Gmail or Office 365), log in there, and then get redirected back to intelliHR and immediately be logged into their account. They won't have to remember a separate set of login credentials for intelliHR.
The following SSO options are supported:
Active Directory Federation Services (ADFS)
Office 365 / Azure AD with the custom SAML connector (requires premium license)
Gmail with a Custom SAML App
