How to Install

  1. Download the latest release; either archive is fine — whatever you're familiar with.
  2. Extract the archive and copy the extracted folder screenlockpin.koplugin into KOReader’s plugins directory.
  3. Restart KOReader. The plugin will appear in the Screen submenu.

How to Use

  1. On your KOReader, open the new Screen › Lock screen submenu.
  2. Set your PIN and configure the options to your liking.

Depending on your settings, the Lock Screen will now appear during boot and / or during wakeup from sleep mode.
If you enable lock on boot, make sure to have some way of file access without unlocking the KOReader, in case you forget the PIN.

A new Lock action is added to the Exit menu, to lock manually (some prefer it over auto-lock on suspend).
Actions for the dispatcher (e.g., Gesture manager) can be found in the Device group.
