You will also be offered the opportunity to sign into, or sign up for, accounts from Google and NOOK. These accounts are optional. If you do not set-up Google or NOOK accounts when you first get your NOOK, you can set them up at any time in the future.
Please note: Your NOOK must be connected to a Wi-Fi network before you can register your device.
The Google account gives you access to the Google Play Store and all other Google applications. Signing up with Google also allows your NOOK to receive and apply NOOK software updates automatically. The Google account is the same as your existing Gmail account. Your NOOK account gives you access your NOOK Library and NOOK content such as NOOK Books, newspapers, and magazines.
You must register your device with a Barnes & Noble or BN.com account, or create a new one. Once registration of your selected accounts is complete, you will be finished and arrive at the NOOK Home screen where you will be ready to access and enjoy all of NOOK's premium services.
