Account Verification Prompt (No Unique Identifier Found) \ If **no unique key attribute** is found (such as **SPUUID, Emirates ID, email, or mobile number**), the system should prompt the user with a question:\ **“Do you already have an account with the Service Provider?”** Depending on the user's response, apply the following flow: * **If Yes**: Prompt the user to enter their **local Service Provider credentials** (username and password) to manually link the accounts. * Apply the corresponding **design guidelines** to support this step and ensure a secure linking process.

## 2. New User Creation **If No**: The Service Provider should initiate **new user registration** by **prefilling the registration form** using the verified data retrieved from UAE PASS. This ensures a streamlined onboarding process while minimizing manual data entry for the user.
