How to Automatically Pre-fill Phone Number in Azure AD B2C User Flow?

Hi all,

We’re using Azure AD B2C for user sign-in and sign-up and have customized the process with custom HTML templates. The current sign-in flow involves three steps:

  1. Users enter their phone number.
  2. Users select their country and phone number.
  3. Users enter the OTP sent via SMS.

We’d like to automatically pre-fill the phone number in the user flow, perhaps by passing it as a query parameter or using another method.

Is this possible? If so, how can we achieve it?

Thanks in advance!

    Hi Koximo! This is the Tech Community Lounge, where users can discuss the platform, not individual product questions. I'm going to move this conversation to the Azure AD board where you are much more likely to get your answer. In the future, if you have product questions, try to find the associated product discussion board. Thanks!
