Enable a password protected lockscreen on your Freewrite
It's easy to protect unauthorized access to your account on the Freewrite. Go to https://postbox.getfreewrite.com/device/settings and click on the toggle next to 'Enable Lockscreen'.
If you see a green check mark like the image below, your lockscreen will be enabled on your account. That means that anytime that you are logged into a Freewrite, a password will be required upon the device waking up. Nobody will be able to access your account unless they put in your password. When you first enable the lockscreen, make sure you connect your Freewrite to Wi-Fi for it to download the setting.
