Prompt used
Identity verification sequence: the user enters their national ID number and gives consent, the service's authentication agency (ASA/AUA) forwards the request to the national ID authority, which sends an OTP to the linked mobile, the user enters the OTP, the authority returns a yes/no plus e-KYC data (name, address, photo) signed digitally, and the service stores only a reference token and the verified details.
