Will Time Machine backup my widget dashboard notes?

Hi

I was wondering if any user can confirm if Time Machine will back up our widget dashboard notes when we do a restore. I have a lot of notes mostly user names and passwords that I use often. My HDD is about to die.

I have written down all the information already but i would feel a lot more comfortable knowing Time Machine will restore everything that I have written so I would not have to input all my information into my widget notes again.

Thanks!
