Hello - has anyone tried hooks to display a Message during an Authentication process? Like a Common message for all SAML/Oauth applications that are sso enabled with OKTA and display Message to the end-users to be aware of an upcoming change.
The Okta inline hooks do not trigger an authentication message to the end-user. The solution here would be to have a modified widget that would check the application context and, if it is a SAML or an OIDC application, it will display the message.
Alternatively, the easier solution would be to modify the Heading under Admin >> Settings >> Customization >> Sign-In Page.
If you are using the developer administrative interface, you will need to switch from top left corner from Developer Console to Classic UI.
