locking widgets

[kmk]

i'm a newbie when it comes to the android phones i just got the droid 2 here recently, and iv let my friends mess with it a little bit and every time i do they go to my social networking widget and change my status so i was wondering if there is a way to stop people from doing so like locking it or something. i know i could just not let them see it but there has been a few times when they have snatched it from me lol so if you got any info plz shoot it my way thanx for your time ^_^ and help
