Eugie, not sure I understand completely. You can change when you put in the password at different time intervals. For example, if you press the power button, and then have the setting set at 30 seconds, if you press the power button before the 30 seconds are up, then you can open the phone without putting in your password.
The glove feature on the Lumia 920 is pretty neat
