How do i reset my password of my nook
If you are talking about the screen lock password, I believe the only way is to to a hard reset. This will unregister the device and erase all local content such as contacts, documents, personal information, books, etc.
1.Ensure your NOOKcolor is powered off; to do so, press the power button for 5 seconds. Your LCD screen should turn off
2.With your NOOKcolor powered off, Hold the Home Key (NOOK "n," logo below the LCD), while simultaneously pressing the Power Button for up to 25 seconds.
3. Your NOOKcolor will begin the start up process, Do NOT let go until a confirmation window appears asking if you would like to, "Factory Reset Your Device?"
4. Press the Home Key to continue with the Factory Reset
5. Press the Home Key again to Confirm
6. Upon completion you will regain access to your NOOKcolor however all account and personal information (email, contacts, pass-code, credit card, etc..) will be deleted from your device. You will then be able to Re-Register your NOOKcolor and re-download any purchased content after your re-connect to your Barnes and Noble account.
