You have a choice to set multiple IDPS for Single Application, i.e integrate multiple IDP and users can select IDP accordingly from which they want to authenticate themselves. There are three different ways to authenticate users using IDP.
- Login using IDP selection page: It gives users an option to Select IDP from the dropdown list during login time.
- Domain Mapping: Here we map the email domains to a particular IDP. So when the user enters the Email address with a specific domain he would be redirected to the respective IDP.
- App Identity Provider Mapping: This feature gives users an option to select one specific IDP for their application before login.
Note : At once you can select either of them.
