Learn more about Joint Accounts

The main purpose of the Joint Accounts is to provide a suitable method of synchronizing multiple reader accounts for the same user, particularly if the user has purchased books from multiple Vendors who support Vendor ID accounts. Again the number of devices is limited to 6 for each Adobe ID account. After two or more accounts are joined, the group as a whole will have the limit of 6, not multiples of 6 devices. To be more specific, the limits are: 6 standalone devices and 6 mobile and tethered devices.


Joint Accounts Workflow


Before joining accounts

Device 1 Device 2
Activated with User1 (Vendor ID) Activated with User2 (Adobe ID)
URLLINK_1.acsm file fulfilled using User1 URLLINK_2.acsm file fulfilled using User2
Book1 downloaded Book2 downloaded


Join Accounts using the portal: http://adeactivate.adobe.com/adept/en/JoinAccountLoginForm.jsp

After joining accounts

Device 3

  • Copy Book1 & 2 to Device 3
  • Copy URLLINK_1.acsm & URLLINK_2.acsm to Device 3


S. NO Scenarios Expected Results
  • Open Book1 using the reader.
  • Reader will prompt for authorization.
  • Enter valid credentials of User1
  • Both the accounts will be synched and reader will be activated. Able to read the book.
  • User1 will be set as default user.
  • Open Book1 using the reader.
  • Reader will prompt for authorization.
  • Enter valid credentials of User2
  • Both the accounts will be synched and reader will be activated. Able to read the book.
  • User1 will be set as default user.
  • Open URLLINK_1.acsm
  • Reader will prompt for authorization.
  • Enter valid credentials of User1
  • Reader will be activated with User1.
  • Fulfillment will happen successfully.
  • Accounts will not be synched.
  • Open URLLINK_1.acsm
  • Reader will prompt for authorization.
  • Enter valid credentials of User2
  • Reader will be activated with User2.
  • Fulfillment will fail. (Since the activated information is cached in the ACS server).
  • Accounts will not be synched.


Should I go with Joint Accounts instead of Multiple Accounts activation? The main advantage is Join Account allows single sign‐on, for example the reader only needs to enter one credential, the reader application can fetch the joined accounts which subsequently enables the reader to read books fulfilled with any of these accounts. And another difference is the reader can sign on to a different device/application with a single account, without re‐entering different account credential multiple times.

Deactivating a device from your ADE account

You can add multiple devices to your ADE account. Having two or more devices registered to the same account is useful if you want to read your book on multiple devices without having to buy it again. However, if you’ve activated too many devices, or if you want to update your OS, or simply need to move to a new or upgraded PC, you may want to deactivate ADE so you can free up your books for more devices or to put them back on the same PC after you upgrade it.  You can deactivate ADE directly from the application.  Here’s how to do it.

Select the menu item Help–> Erase Authorization.

While deactivating in ADE 4.0.3, the user has to provide valid user credentials to deactivate.




For Vendor account, the user has to provide both the User name and Password by selecting the vendor.


For Multiple or Joint Accounts, each accounts needs to be deactivated separately.

Adobe Digital Editions – Anonymous Activation

If you do not have an Adobe id, and want to get right to reading the book, you can choose to authorize your device without an ID. You can continue to download and read all books in this utopian environment, as long as you don’t need to transfer these books to a different device, or you de-authorize ADE. Now if you wish to do one of the above, and still preserve access to the books you’ve currently downloaded, follow the steps below:


So this gives rise to the question: If I have activated ADE without an ID, is there a way to activate with an Adobe ID and continue reading books fulfilled using the anonymous account, and also move the books to other devices? The answer is YES, but there is a catch. You can achieve it, by creating a new Adobe ID and activate ADE again directly without de-authorizing the existing anonymous account. The catch here is, it should be a fresh Adobe ID which is not activated on any other device or computer.


I have an Adobe ID and am using it on another machine. Is it possible to associate the existing ID with the anonymous account?” No, because once an ID is activated, a unique UUID will get associated with this user account. In the fresh ID case, it will be associated with the UUID of the Anonymous account. “Do I have to maintain both the accounts?” You can join your existing account with the newly created account, which will allow devices activated with one Adobe ID (or Vendor ID) to read books previously fulfilled with another Adobe ID (or Vendor ID).

A sneak peek at what’s new in RMSDK 11

Adobe is glad to announce what’s in store for the RMSDK users as we made considerable progress for the upcoming RMSDK 11 release. One of the most exciting news is that RMSDK is going to support EPUB 3 in the new release. Apart from this, there are significant enhancements in the new release to support seamless EPUB 3 support to users. At the outset, RMSDK 11 is going to support EPUB 3.0 along with its four specifications, using Readium SDK:

  • EPUB Publications 3.0
  • EPUB Content Documents 3.0
  • EPUB Open Container Format 3.0 (OCF) and
  • EPUB Media Overlays 3.0

Why EPUB3 support?  As of date using RMSDK 10, users are unable to read eBooks in EPUB 3 format. EPUB 3 is the latest version of EPUB, the widely used open standard for digital publications based on latest web standards including HTML 5. EPUB 3 is more powerful and allows users to create more engaging content with the help of audio, video, svg, MathML, media overlays and so on. Within a short time, EPUB 3 is going to be universally supported as it has enhanced layout and accessibility features. For Adobe customers it is a great opportunity to adopt EPUB3 early on, with this new release of RMSDK 11.

This video demonstrates MathML and Video playback content support in EPUB 3 format:

Enhancements in RMSDK 11:
API functionality

RMSDK provides API for functionalities like loading an EPUB document, navigating through it, rendering a particular page on a given bitmap buffer and so on. In addition to these features, RMSDK 11 would provide APIs to support EPUB 3 features like media overlays, audio, video and so on.

Support for Readium based documents

RMSDK 11 implements an additional document provider for supporting Readium based documents. You need to register this document provider using the new API. Using new APIs provided in this release, you can enable/disable Readium document for the calls. Client can also query if the given document object is readium based, using the new APIs.

Rendering EPUB document page

You can render EPUB document page using RMSDK 11. Create a renderer object for the EPUB document. Use the new API to query if the document has any media overlays. The new API allows the client to control the lay mode (stopped or playing) of the media overlay.

Platforms supported

  • MAC 64 bit
  • iOS ARM v7, v7s, 64
  • Andriod ARM v7a

EPUB3 based readers from Adobe

Lady reading an ebook

While EPUB3 has provided the standards for developing rich and engaging ebooks, it will not achieve mainstream adoption till publishers adopt it, eReaders support them, and quality tooling is provided to help produce EPUB3 documents.

The upcoming release of Adobe Digital Editions (ADE) and Adobe’s Reader Mobile SDK (RMSDK) is a step towards helping publishers make this transition by fully supporting content rendered in the EPUB3 format, along with support for EPUB2 and PDF in the same reader. ADE and RMSDK are also designed to be compatible with the recently launched InDesign CC EPUB 3 fixed-layout support. In addition to adding the EPUB3 rendering capability, Adobe will also be introducing new DRM models to facilitate innovative distribution of content and help expand the market.

While the commercial launch is scheduled for this Fall, we invite you to try out your content on the current pre-release version. You will find support for fixed layout and reflowable, audio and video playing, MathML, JavaScricpt in and outside of iFrames, TOC and page-list, multi-ePub, embedded fonts, and more of the EPUB3 standards.

Email us at ebooks@adobe.com to receive an invite to the pre-release. Further, if you are interested in building your own eReader apps based on RMSDK, and would like to be considered for the beta, please mention this in your mail.
