Can the sign-up form be bypassed when signing in with a social IDP using a custom policy?

Question

I am using a B2C custom policy to sign in using the social IDP of Entra ID. It fetches all the needed claims from the IDP and then shows a sign-up form with a display name and given name. Can I bypass the step to show this form and have it directly create a user on B2C with the fields fetched from IDP? I don't want the user to see the sign-up form since the policy already has all the required fields from the IDP. Can it automatically create a user on B2C?

Hi @Aditya Gour (NAV India)

Thank you for posting this in Microsoft Q&A.

No, it is not possible to bypass the sign-up form and automatically create a user in Azure AD B2C using the claims fetched from the social IDP in your custom policy.

If a social account is not present in Microsoft Entra storage, users will be directed to the sign-up process.

Hope this helps. Do let us know if you any further queries.
