Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
You may have to reset your Nook, unfortunately, if you have no note of your password ***** access to it.
To reset it, try this:
Hold the Home Key ( “n,” logo below the screen), pressing the Power Button at the same time, for up to 25 seconds.
The Nook should begin the start up process, and don't let go of the buttons until a confirmation message appears, asking whether you would like to, “Factory Reset Your Device?”
Then you answer in the affirmative, and the Nook will be reset back to factory conditions, erasing anything that is on it, but returning the password ***** a default status.
Let me know how that goes, please.
