We have an Azure AD custom policy that uses totp flow to generate a passcode. Users use Microsoft authenticator . If b2c user lose/change their device, the only way we can re-register MFA through the authenticator app is to remove that b2c user and ask them to sign up again. This initiates the user signup workflow and provides the QR code to user so that they can add it to the Microsoft authenticator.
Is there a way in B2C custom policy, we can enable users to reset their MFA authenticator i.e. like password reset can we do MFA reset.
Thanks for your help
