# 3. Deregistration Workflow

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

## **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.
