MFA phone number does not appears in token claims after sign up

Question

i have applied the MFA on sign up using custom policies following this MFA using custom policy,
MFA working fine,

i have added following claim in relying party

<OutputClaim ClaimTypeReferenceId="strongAuthenticationPhoneNumber" />
<OutputClaim ClaimTypeReferenceId="strongAuthenticationPhoneNumber" PartnerClaimType="phone_number" />

but i am not getting strongAuthenticationPhoneNumber as claim after sign up, but when i sign in with this created account it shows in the claims.
i want to have strongAuthenticationPhoneNumber in claims immediately after sign up.
i am using jwt.ms for quick viewing of claims

Answer 1

During signup, the phone number can be found in the claims reference "Verified.stringAuthenticationPhoneNumber".

Therefore you can also add this output claim in addition to the one you already have:

<OutputClaim ClaimTypeReferenceId="Verified.strongAuthenticationPhoneNumber" />
