We have a User ID signup and use the built in Azure B2C userflow (sign-up and sign-in) During the sign-up we give the "username" input but the same is not returned as a claims. and there is no option to select username to return as a claim.

Hi @Korodi, Ashith Vijay • Yes, the username claim is not returned by default and there is no out-of-box option to add it as an output claim to be passed to the application. As of now, the only options that you have is: Use custom policy rather than user flow. Create a custom attribute to capture username and then pass that in the token. You can also post feedback at https://feedback.azure.com to add this option in the user flows as well. These feedbacks are monitored by the product group for feature enhancements.

@Korodi, Ashith Vijay • After you assign a value to the custom attribute via Graph API, you will need to update select the checkbox of the custom attribute under the Application Claims blade in your user flow. Any old user who has this attribute with a value assigned will get it as a claim in the token. Keep in mind that the claim will be returned as extension_username in the token if you named your custom attribute username.

I tested your scenario by performing the below steps:

Signed up with a new account using signup/sign-in username flow.

Then added a custom attribute.

Used graph API to update the custom attribute for the user.

Selected the checkbox for this custom attribute under Application Claims blade.

Signed in with the user created in step with using the same signup/sign-in username flow.

Verified that the custom attribute is returned as a claim in the token, as highlighted below:

Thanks!
Unbelievable that something as basic as getting uername into a token is so complicated. Quite a deal breaker.
