Deregistration Workflow If you choose to remove your record, you may select the **"Deregister Facial Identity"** option after logging in.

Users with an active "Already Registered" status can initiate the removal process by selecting the Deregister Facial Identity button.

## **Process and Execution** Upon selecting this option, the system removes your record from **Entrance Terminals** and updates your registration status. ## **Security Cooling-Off Period** To maintain system integrity and ensure all campus gates are synchronized, a cooling-off period applies to mobile deregistrations. {% hint style="info" %} **HKU App:** If you deregister via HKU App, you may re-register starting from the next calendar day. **Workstations:** No cooling-off period is required for on-site requests. You may re-register immediately at any physical workstation. {% endhint %}
