Thanks for all of these. I like the fact that with #81 and #80 you followed the brief. I think the font is too cartoonish though. I like the cleanness of #73. Not sure I like the lock though as it is too prominent and makes me look like I am a locksmith or something. But overall, nice work! Oh, and I think I like the line under the name like in #81
I like #73. Is there a way to get it with a "more professional" font? Keep the lock. That could work...unless you have a different version. I like that you put a check mark in it to denote results. Nice work!
