file2password is a utility that allows you to select a file (picture, document, music, etc.) and generate a secure password based on it. This means that there is no need to remember any password - just a picture or a filename. It is small (2 KB plus CSS), highly secure as it does not upload or shows the file used, supports drag and drop, can use online storage, and requires no server-side scripting.
