Hi please see the above video after three failed attempts of the passcode, should have option to use your B&N account password XXXXX disable the passcode.
If that does not do the trick , then will need to factory reset your Nook . As follows:
Will then need to re-complete the registration and reload the books from your account to your nook.

Hmmm, Ok well lets double check the reset process;
1.Ensure your NOOKcolor is powered off; to do so, depress 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 depressing 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?" This will De-Register as well as erase all content and information on your NOOKcolor (Including the 4 Digit Pass-code 4. Depress the Home Key to continue with the Factory Reset 5. Depress the Home Key again to Confirm 6. Your device will now begin the clearing process. 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 start anew
