This might be the most secure method for locking smartphones

Have you ever held someone’s BlackBerry phone and saw a grid of numbers – like in a Sudoku game? It is quite perplexing. The first day I came across it, I asked, “What is this?”, “It is a kind of security lock”, the reply I got. The feature we are talking about is called BlackBerry Picture Password. How does it work? How do we set it up? Read on:

Basically, this feature lets you combine a number and a picture to unlock your BlackBerry, instead of the regular passwords we are used to. Setting it up is easy too:


  • Pick a number
  • Drag the number to a location on the picture and Press OK. ( This is the unlock combination)
  • To confirm, you drag the number to the part of the picture you earlier chose.
  • That’s all.


To unlock this would be difficult, unless one know the number you chose, and then the location on the picture where it should be placed. That already sounds like a mission impossible.

Please note that the Picture Password feature works only on BlackBerry 10 devices.


  1. Err, but many people are still using BB OS. Just as there are people still using Symbian devices.

    Being a dying OS is no reason why this information won’t be useful to some.

  2. I saw it last year and fell in love with it immediately.
    I wish I can get it on my android.
