How to implement supertoken as sso server or account server in many apps client ?

hey <@645478302416633876> - do you want to do SSO for different apps within different sub domains (sub1.a.com vs sub2.a.com)? Or different apps across different domains (a.com vs b.com)

Maybe I can use SSO for different subdomain or different domain, because I can implement this on any app or services
But now this app & service is on design

right. So different sub domains is possible today, but different domains is not cause we are not yet an oauth provider

Can i get the documentation or any reference for implementing in subdomain?

Yea. So it’s the standard way of setup, except that you should enable session sharing across sub domain (search our docs for session sharing across sub domains)
