SSO between two apps in the same tenant but leveraging custom UI

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.

Thanks!

Hi @akash.verma,

Welcome to the Auth0 Community!

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.

With that said, I encourage you to consider migrating from Embedded Login to Universal Login or vice versa to accomplish SSO.

Please let me know if you have any further questions. I would be happy to assist.
