Azure AD Claims - Retrieve username

Question

I am using a web application and AAD B2C for authentication purposes. How can I add a claim to find the username that was used to sign up?

Answer 1

You can retrieve the username by making a call on AD graph API. That is the only way to work around it as Azure has as of now not made it available for the username to be passed down as a claim. 

An extra trip will have to be made to retrieve the username, which is an issue that may be solved by including the username in the JWT itself.
