I originally recommended this program in 2011 and am including the original post below. I still use this program daily and highly recommend it!
REVIEW: I started using 1Password after the "great computer crash of '10. It's an easy-to-use program that stores not only your passwords, but identities, secure notes, and software info (licenses, confirmation emails, etc).
They offer a 30-day free trial and the program is very reasonably priced. (Prices vary based on the gadget / operating system you are using.)
They make a version for Mac, Windows, iPhone, iPad, and Android.
This program saves me so much time each day. No more searching for passwords, logins, or filling out online forms!
