To enable the screen lock: iDoceo's main screen > Gear icon (top bar) Security
Enable it and then type a numeric PIN with 4 to 8 digits
You can define the minimum time required for the screen lock to appear.
Upon iDoceo's startup or if coming back from a different app in your iPad, it will show this unlock screen. Type your PIN and then OK to unlock it
iDoceo is an offline application and therefore does not offer a password reset function.
