1Password is much more than a password manager for the Mac. It can manage passwords for websites and notes and store you credit card information securely, but it can also do so much more. It really shines when used in conjunction with Safari and/or Firefox. 1Password will automatically fill-in any site login fields once you provide the master password for 1Password. Another great feature is the the applications synchronizes with a companion application on the iPhone. I’ve been using 1Password on the Mac for about 6 months and find it more and more useful everyday.
