PasswordMenu for Mac

From Citrus Software, Inc.:

PasswordMenu is a simple but powerful application that allows you to store all your passwords securely in the menu bar. This way your most important passwords are always just one click away. Just select any item from the list, enter the master password, and the password is copied to your clipboard! If the login/password belongs to a website, PasswordMenu automatically launches your browser and loads the website. A little reminder window will show your username for that website. Don't worry about spying eyes, there are no passwords stored in the menu bar, only the names that refer to the passwords. On top of that the menu is password protected with your OS X admin password. Still unsure? Try it and you will not want to miss it anymore.
