Sometimes we may have too many password to remember. Drop everything and free our mind? Not yet without dropping password down in a secure way. Try KeePass. It is an open source password manager which helps you manage your passwords in secure way. The database are encrypted with good encryption algorithms (geeky terms they are AES and Twofish):
… Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your homepage’s ftp password, online passwords (like CodeProject member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem… A serious problem. The thief would have access to your e-mail account, homepage, etc. Unimaginable.
KeePass is a free/open-source password manager or safe which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key-disk. So you only have to remember one single master password or insert the key-disk to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish)…
For even simpler password management on OS X, just create an encrypted disk image with a simple text file listing the usernames and passwrods for the site. Then create an alias to the password file on your desktop. when you try to open the alias on your desktop, it opens the disk image and preesents you with the password.
Secure and simple!
If you need a password safe that is portable among OSes and can be run from a USB stick, try JPasswords: http://jpws.sourceforge.net/jpasswords.html. Requires Java, though.
The best tool I came across so far: http://passwordmaker.org
Requires no download, no software install (but the firefox plugin rules), no secret files, its unhackable… All you need is a master password.
