Validate SMS code without signup

Hi,

We want to validate the SMS code without creating the user if the user is new. We want to control the creation of user from our backend API programmatically.

Based on our use case, we don’t want the user created if they don’t already have an account as there are other steps we need to perform during creation.

We can achieve this with okta factor sequencing and wondering how we can achieve this in Auth0.

Thanks

Any insight on this? Since we can use Twilio as the provider to send the OTP, was wondering if there’s a way to use the Twilio’s verify (Auth0 integration) API to achieve the use case?
