To **change the PIN** **after** it has **been set**, **disable** the **Unlock with PIN checkbox** in settings, then **reenable** it.

This will **require** a **new PIN** to be entered.

#### Use Unlock with PIN

When the Browser Application is **locked**, you will be **prompted** to **enter the PIN** to **unlock**.
