01Standards create room to grow
Applications can arrive with different authentication requirements. OIDC and SAML provide established federation paths, helping organizations connect supported services without designing an unrelated login arrangement for every application.
02More than one identity starting point
Different populations, partners or acquired businesses may use different providers. Multiple-IdP support creates room to design appropriate trust relationships instead of requiring every identity source to change at once.
03Make the trust relationship intentional
Agree application expectations, exchanged attributes and authentication requirements. Federation delivers more value when the identity received at sign-in can be understood in the context of the access being requested.
