The Passcode Lock is a 4 digit code that adds a level of security to the ArtBinder application on your iPad. When on, you'll be required to enter your personal passcode each time you start the app and during app updates. To enable/disenable, click the Setting gears tab in the ArtBinder app. Scroll down to "Passcode Lock" and toggle on or off (green is on).
We highly recommend using the passcode lock if you store sensitive pricing data on your app.
