One of the many problems with keeping secure is that when you use a strong password, it can be hard to remember and annoying to input. This commonly leads to people either using a weak password (easily guessed or brute force attacked) or circumventing the security (by never locking their Mac).
Rohos offers an interesting alternative. You can take any old USB thumb drive you have and it will act as your authentication for unlocking your Mac. As an added bonus, it encourages locking by doing so automatically when you remove the device from your computer.
In essence, the software allows you to create a physical key that you need to plug into your Mac in order to unlock it. You could even attach it to a keychain. Very clever. Rohos Logon Key for Mac costs $29.
