Don't tell anyone you got this from me, but chrome://settings/passwords is the only address you need to access anyone's passwords from their computer, if they use Google Chrome. Check it out for yourself!
Weird, huh? For the other ways people might access your private info, try Private Calculator. It works like a calculator, but enter your password and you'll be taken to a secret file management system that accepts files from your computer (via Wifi) or even without an internet connection (via iTunes). Today it drops from $1.99 to FREE.
