Authorising Adobe Digital Editions (ADE) with an Adobe ID

In order to transfer your DRM protected ebooks to your ereader device (such as Nook, Sony, or Kobo) you first need to authorise both Adobe Digital Editions (ADE) and your ereader device using an Adobe ID (this is not the same as your account details).

If you do not authorise both devices you will still be able to download and read your ebooks within ADE, but it will display a CE_COPY_NOT_ALLOWED error if you try to transfer them to an ereader.

Please also note that if you have already downloaded DRM protected books and then authorise your ADE, the authorisation will not apply to the books you have already downloaded. So if you then try to transfer these books it will not work. You will need to fully authorise ADE, then delete these books from your bookshelf and redownload them so the authorisation can be applied at point of download.

If you have not already done so, please first install Adobe Digital Editions on your computer. Note you only need to install the program once, so if you have already installed ADE on your computer you can skip this step.

Then to authorise Adobe Digital Editions please follow these steps

  1. Open ADE on your computer
  2. If you have a book open, please click 'Library' to return to Library view
  3. Click 'Help'
  4. Click 'Authorize computer...'

On the next screen it will ask you to enter three fields, an 'eBook Vendor' and your Adobe ID and Password.

For 'eBook Vendor', please leave this as 'Adobe ID'. If it doesn't say 'Adobe ID', please select it from the drop down menu.

If you already have an Adobe ID, please enter your Adobe ID and Password in the remaining fields and click 'Authorize'.

If you don't have an Adobe ID already, please click the link 'Create an Adobe ID'. This will navigate you to Adobe's website where you can register an Adobe ID (or you can click here). Once you have done so you can then enter your Adobe ID and Password in the remaining fields and click 'Authorize'.

Please be sure to make a note of your Adobe ID and password in case you need to deauthorise your computer and reauthorise a new computer.


If you also need to authorise your portable ereader device please also see our article on Authorising an ereader device with an Adobe ID.
