How do you password protect your Xbox 360?

Set an Xbox LIVE pass code

1. Go to My Xbox, and open your profile.
2. Select Manage Account.
3. Select Xbox LIVE Pass Code.
4. On your controller, enter a four-button code by pressing X, Y, the triggers, the bumpers and the directional pad.
5. Enter your code again to confirm it.

To reset your pass code, repeat this procedure at any time.

Note If you want to create a new Xbox LIVE pass code, you have to enter your original Xbox LIVE pass code and then reset the pass code.
