I am using AdB2c custom policies.

I want to update a user's email signin identity or mobile sign in indentity using custom policy UI.
Is it possible ?

    Hi @Abhay Chandramouli , I don't have any samples for this currently available bit I can help walk you through it. You would need to use the Graph API for this. This thread details how you can set this up. An example of a call you can make to update a user's email follows:

        "identities": [  
                "signInType": "emailAddress",  
                "issuer": "{tenant-name}",  
                "issuerAssignedId": "{user-signIn-email}"  

    as detailed here. Please let me know what questions you have about this and I can help you further.

    Thank you,
