Change User Settings
You can change settings associated with user accounts. For example, you can make the primary email address for a user account a required or optional attribute.
By making the primary email address optional, if Oracle Identity Cloud Service integrates with another cloud service or on-premises application, then a user’s email address can be propagated from that service or application back into Oracle Identity Cloud Service, and designated to be the user’s primary email address in Oracle Identity Cloud Service.
To change user settings, you must be assigned to the identity domain administrator role or the security administrator role.
Note:
You must sign out and sign back in to the Identity Cloud Service console for the change you made to the Allow primary email address as optional switch to take effect.
