You can lock your Ploom X Advanced device with an unlock code made up of button presses and slider movements - so only you can unlock it. 

Here's how to set it up:

1. Connect your Ploom X Advanced device to a power source using the USB cable provided.

2. Open and close the cover.

3. Then, press and hold the button until your Ploom X Advanced device vibrates.

4. The light will flash for around 20 seconds. While it's flashing, create a short sequence of button presses and/or slider movements. You must use a minimum of 3 and a maximum of 10 movements. This will be your unlock code.

5. Open the cover and close it again. Your password is all set up.
