If you don't have one you can create an Adobe ID and password. You can activate up to six computers and devices where either Adobe Digital Editions or an app like Bluefire or VLE books app is installed and authorized with the same Adobe ID.
If you select Don’t Authorise Computer, you cannot transfer an Adobe DRM (Digital Rights Management) protected ebook that you have downloaded to Adobe Digital Editions on your device.
