This new version adds two more locking types, bringing the number of ways you can lock your mac to four… and one option not to lock at all. This was added mainly for simplicity for users:
Lock using TokenLock
This is the simplest lock, and just throws up a screen with the TokenLock logo and an area where you can enter your password to unlock. (Or bring your device back in range/plug your device back in)
Lock using Display Sleep
Similar to Screen Saver lock, this simply puts the display to sleep.
It also fixes compatibility for 32bit and OSX 10.6 systems.
For first-time users we changed the initial screens to ask whether you want Power or Simplicity and based ont he answer, we preset some things for you.
