Azure B2C verify username and password

I'm working on some webapis. With B2CGraphClient I can create an user, update or delete it.

My problem is how I can verify username and password. I read Microsoft documentation about it but this case is not covered.

Scenario

From an app the user sends its credentials (username / password). This credentials are stored in Azure B2C. I should call B2C and pass to it this credentials and receive if the user is valid and authenticated or not.

Currently, Azure AD B2C doesn't have any direct support for this.

However, work to support for the Resource Owner Password Credentials flow in Azure AD B2C is in-progress.

This new feature will enable apps to collect a user credential and POST it to the B2C tenant for validation.

5 Oct 20: UPDATE

Support for the Resource Owner Password Credentials flow has been implemented for Azure AD B2C's built-in flows and custom policies.
