'Store "mobilePhone" in contact info during registration - Azure AD B2C Custom policy + MFA

How to store mobile Phone Number during SignUp/Registration with MFA in Azure AD B2C Custom Policies. What is the claim name that we can use to refer to mobile Phone



Solution 1:[1]

You can access and store a mobile phone by using the "mobile" attribute here.

To actually implement this you would need to follow the steps in this document. For example, the linked code adds a "city" claim, you would need to replace "city" with "mobile"

<!-- 
<BuildingBlocks>
  <ClaimsSchema> -->
    <ClaimType Id="mobile">
      <DisplayName>Mobile Phone</DisplayName>
      <DataType>string</DataType>
      <UserInputType>TextBox</UserInputType>
    </ClaimType>
  <!-- 
  </ClaimsSchema>
</BuildingBlocks>-->
