Azure AD B2C SSO and Teams app

KT 130

Hi all,

We are developing a Teams tab app. Our backend application is authenticating users with Azure AD B2C.

How can the users log in to our application via Teams Tab app? Any sample code or document? I can find find only Entra ID SSO with Teams App.

@Vikram Boorla (Tata Consultancy Services Limi) , thanks but I don't understand how I can use it. In the first place, is it possible to use Azure AD B2C in Teams tab apps?

The doc says "Customer-owned apps: SSO is also supported for customer-owned apps within the Azure AD B2C tenants", but it did not explain how to do it. The application side is already developed with Azure AD B2C, so we would like to use Azure AD B2C for Teams Tab app.
