KeePass is a free, open-source, light-weight and easy-to-use password safe for Windows.

You can store your passwords in a highly-encrypted database, which can only be unlocked with one master key and/or a key-disk.

A database consists of only one file that can be transferred from one computer to another easily. The program supports password groups, in which you can sort your passwords into.

You can drag-n-drop passwords into almost any other window. The auto-type feature types your login information into other windows automatically (just press a hot key). Fast copying passwords or user names to the Windows clipboard is possible by just double-clicking on the specific field in the password list.
