How to change layout or info on a password screen?

view story

http://androidforums.com – I am kind of new to android phone. I am not sure how to do this. I have an ActiveSync account and the Active server requires a password. So I have to enter a password in order to enter the phone. I saw many locker screen apps in Google Play and it appears that they are not for password screen. Basically, I hope to enlarge info on the screen that requires password entry. Any way to do this? Thanks for any help! (General)
