Is it possible to have multiple custom domains?
If so, can we have sso across these custom domains?
Our use case:
we have 2 groups of apps, one group needs to have example.com as a custom domain and other group needs to have example2.com. Is it possible for both groups to have sso regardless of custom domain used?
Hi @dinesh,
Have you looked at this article:
It demonstrates SSO across domains.
Hope this helps!
Thanks,
Dan
yes, I just want to confirm that to implement sso, is it must to have a common domain(accounts.google.com) or are there any other ways?
