Locking of Micromax Q1 by password protection

Hello,

with due respect i would bring in your kind attention that I have purchased a Micromax Q1. As I dont have any idea how to lock it by password protection, can you put some light on how to make it password protected.

Please, would you please kindly throw some light on my request so that i can lock it using password so that no one else can use it in my absence

Thanking you
With regards
