Being BlackBerry 10 users; chances are we are all a little security conscious, particularly if you use your device for business. God forbid you lose your trusty BlackBerry Z3, but if you do you'll want to ensure you have a password set up on it so whoever finds it, or steals, won't have access to your personal information.

Like all BlackBerry 10 handsets, the Z3 has a couple of options when it comes to which sort of password you use.

First up is the simple numeric one where you just key in the number combination you have chosen. Although most smartphone users rely on this option it isn't 100% secure as you can easily observe a friend, or stranger, unlocking their phone.

To set up the standard password follow these steps:

  • From the home screen, swipe down from the top and tap on Settings

  • Scroll down to and tap on Security and Privacy > Device Password

  • Toggle the button for Picture Password to On

  • At the Device Lock prompt, input your device password

So BlackBerry came up with an even more secure way of doing things - Picture Password. Here you will need to drag a pre-chosen number to a specific part of the Z3's screen in order to unlock the device. The set up process is nice and straightforward and you can't really go wrong. The chances of someone guessing your unlock code now is pretty much impossible as Kevin put to the test some time back.

Follow these on-screen directions to setup your picture and number combination:

  • Choose an image from the default gallery or your picture library

  • Select a number (0-9) from the grid

  • The number selected will be highlighted on the display. Drag this number to a specific point on the picture

  • You have now setup your picture password unlock combination

  • You will be asked to confirm your selections by re-entering your picture password combination

So your BlackBerry Z3 is super secure in terms of messaging, but it's also got the highest level of security required just to unlock it - some great reassurance.
