I have two Apps (App A & B) in the same tenant. App A is using custom UI login while B using the universal login page. I have a use case to SSO from App A (Custom UI login) to App B (universal login). Is this possible as the domains will be different for the Auth0 cookie? If yes, how to approach this.
I understand that you have questions regarding SSO between your applications.
Given that you have the first app using the Universal Login and the second app is using Embedded Login, and on different domains, this will not be possible. Having your applications on different domains mean that they cannot share the same SSO cookie. Therefore, it’s not possible to implement SSO across your applications.
