Hi @Ronnie Kapoor · Thank you for reaching out.
You can use the sample: A B2C IEF Custom Policy which allows login via Phone Number (OTP). The sample is based on the Base and Extension from the SocialAndLocalAccountsWithMfa Starter Pack. You can chain the TrustFrameworkLocalization.xml file to TrustFrameworkExtensions.xml file in the SocialAndLocalAccountsWithMfa starter pack.
Note: This sample is in private preview.
