To enable PIN password security, go to Settings >> User Interface and check Password.
A screen will show up for setting a 4-digit PIN password.
It is important not to forget the PIN as you will not be able to access your Bluecoins app without it.
Bluecoins supports newer phones with built-in fingerprint authentication. Bluecoins will recognize a user fingerprint registered in the phone settings. Simply use the registered fingerprint for accessing the app.
