SSO for Microsoft Teams custom tabs?

Question

Hi,

I am building a custom Tab for my web app inside the Teams application. My web app supports Google SSO for login.

I have seen many other apps provide only Microsoft SSO for tab authentication. Is there any limitation that the custom tab supports only Microsoft SSO for authenticating users?

Hi @Veera

There are some important restrictions that you must know:

• Only user-level Graph API permissions are supported that is, email, profile, offline_access, OpenId. If you must have access to other Graph scopes such as User.Read or Mail.Read, see recommended workaround.
• It is important that your application's domain name is the same as the domain name you have registered for your AAD application.
• Currently multiple domains per app are not supported.
