The 3.0 version of 1Password for Mac just came out–it is still in beta (test) version, but it’s stable enough to use regularly. And it’s the only version that works with Snow Leopard.
I recently installed it and have been putting it through some paces. It looks much fancier, including mini icons for most of the web page logins it stores, so you can identify Google or Amazon or Facebook by the icon alone.
Check out the Wallet feature: It allows you to store your bank account info, credit card numbers, and other personal data completely securely. So it’s always right at your fingertips when you need it.
So 1Password is really the place to store all your sensitive info.
