This setting changes the conventional user name and password login to user name, followed by another administrator-configured factor to log in.
Note:
This option appears only if passwordless authentication is enabled. If this option doesn’t appear, then contact Oracle Support to enable passwordless authentication.
If you turn on the Enable User Name First switch, then users will be shown two pages when they sign in to Oracle Identity Cloud
Service. In the first page, the user provides their user name, and then clicks Sign In. Oracle Identity Cloud
Service evaluates the criteria in the identity provider policies to determine which identity providers and local authentication factors (such as Email, Mobile App Notification, Mobile App Passcode, Text Message, or User Name-Password) will be available to the user to sign in to Oracle Identity Cloud
Service. These identity providers and local authentication factors appear in the second page. The user uses one of the identity providers or authentication factors to access Oracle Identity Cloud
Service. See Add an Identity Provider Policy to see how you can configure login options for users.
If you turn off this switch, then in the Sign In page, the user can authenticate into Oracle Identity Cloud
Service either locally, by providing their credentials (user name and password), or by using a SAML or social identity provider.
