Password manager
I have been experimenting with a password manager for Mac OS X that I really like and have found quite useful. It is called 1passwd and can be downloaded from http://1passwd.com. You can use the "demo" version which allows 1 identity and up to 12 passwords but I think after doing so, you will find it worthwhile to pay for the full version. In my work, I have several government sites that I frequent regularly and each has a different login and password. 1passwd makes it a breeze for me to sign in without having to look up each of the different combination of logins. The program also come with a built in password generator. Try it out. The developers offer a 30 day money back offer so you really have nothing to lose.
