Why did Microsoft CardSpace fail?Edit
Microsoft announced this week they will not ship CardSpace 2.0. They giveonly a little bit of reasoning here:http://blogs.msdn.com/b/card/arc....
What went wrong?
Beyond Windows CardSpaceRATE THIS
Identity and Access Team15 Feb 2011 7:59 AM

For several years Microsoft has advocated the claims based identity model for more
secure access and use of online applications and services. With enhancements to our
existing platform, such asActive Directory Federation Services 2.0andWindows
Identity Foundation, weve made progress in that initiative. Claims-based identity is
used widely inside Microsoft and is now part of many Microsoft products, such as
SharePoint, Office 365, Dynamics CRM, and Windows Azure.
Microsoft has been a leading participant in the identity community and an active
contributor to emerging identity standards. We have increased our commitment to
standardization activities and added support into our products for the SAML 2.0,
OpenID 2.0, OAuth WRAP and OAuth 2.0 protocols.
There is one component of our identity portfolio where we have recently decided to
make a change. Windows CardSpace was initially released and developed before the
pervasive use of online identities across multiple services. Perhaps more
importantly, we released the user component before we and others had delivered
the tools for developers and administrators to easily create claims-ready services.
The identity landscape has changed with the evolution of tools and cloud

participants, we have decided not to ship Windows CardSpace 2.0.
Claims-based identity remains a central concept for Microsofts identity strategy,
and its role in our overall strategy continues to grow. Furthermore, we are not
abandoning the idea of a user agent for exchanging claims. As part of our work on
claims-based identity we are releasing a new technology preview of U-Prove.
Thisrelease of U-Provewill take the form of a user agent that takes account of cloud
computing realities and takes advantage of the high-end security and privacy
capabilities within the extended U-Prove cryptographic technology.

It failed because of several reasons:
It had very poor usability and required the user to either useWindows VistaorWindows 7or install .net3.5
It had accessibility issues and was desktop bound, i.e. couldn't be easily used across other operating
systems and in particular mobile devices (yes a fewiPhoneprototype selectors exist but they didn't
work on theBlackBerryfor example)
It was inherently tied toActive Directoryand so made a consumer use model very difficult (if not
impossible in reality) to implement
It had no true facility for utilising verified claims through a trusted third party and then populating
those claims in real time through a third party
Resolving those issues has been our goal in my company because the underlying
technology of Information Cards is the best representation of a 'true' identity (i.e.
something that can transact, in real time, verifying information about ourselves) we have
at this current time. We now have a fully Cloud based cross platform/device
implementation of Information Cards that is a new wave and fixes those issues and goes
beyond the original remit of the system (Information Cards 2.0 if you like)

I guess here are some reasons I can think of:
1. Wrong product. This should have been a seamless feature of IE, not a separate product.
2. Wrong implementation. WS-* meant that half (or more) of the market wouldn't touch
it.
3. No go-to-market strategy. Maybe there was one, but I never saw evidence of one.
4. No smooth upgrade/downgrade path. The brave new world did nothing but confuse
users and developers alike who wanted to continue supporting their existing users withexisting technology (i.e. username/password)
5. Misunderstanding of requirements. All sites want e-mail addresses. There's no point
creating all this wonderful privacy-protecting technology if it is used each time to
exchange globally unique e-mail addresses.

Cardspace suffers from being associated with a deep over-generalisation at the heart of
the Identity Metasystem, that has distracted, confused and demoralised many
stakeholders who tried to give federated id a go. Ive seen four different well funded
authentication broker schemes in Australia overpromise and underdeliver (or fail
altogether). A proper post mortem of Cardspace will look at its common problems with
that other recent casualty in the identity wars, OpenID (which struggles to meet
expectations even in near trivial authentication settings).
Infocards are a brilliant UI. They reify and normalise the important notion ofplurality of
identity. But a great new UI should never have been mashed up with the radical Identity
Metasystem.
If we simply used Infocards to take our perfectly good current identities online - like
credit card numbers, social security numbers, health identifiers, and proof of age cards -
we would achieve great things. But it was unhelpful for Infocards to get tangled up at

the same time in federated identity and the attempt to re-cast banks, govts, telcos etc. as
open Identity Providers. Inserting IdPs into otherwise bilateral relationships between
customers and service providers is truly a massive change to the way we do
business. Breaking open identity silos entails re-engineering risk management
mechanisms, re-writing user agreements and contracts, and in the case of banking, re-
legislating to modify Know Your Customer rules. Despite easy intuitions about re-using
identities, federated identity is a dramatic paradigm shift that is not warranted in many
cases for solving the problems of ID theft and the password plague.

Let's unpack the opening paragraph of Wikipedia's entry on Windows Cardspace
:
"Windows CardSpace ...
This says Cardspace is not a stand-alone entitity, but a noun terminally modified by its
owner's brand.
... (codenamed InfoCard)...
More blurring. Cardspace had way too many names and related nouns over the years.
Infocards (or werre they "information cards"?) needed a stand-alone label, a noun of their
own. This never happened, at least not so the subject was easy to talk about.
...is Microsoft's client software...
No 'fence to Microsoft, but its very name is aversive to all developers other than ones
already in the MS ecosystem. Even though Microsoft was more open-source-friendly
around Cardspace than around anything else I can think of, it still had a huge taint to
folks in other communities. For example, Linux Journal ran a long and very friendly piece
about Cardspace (not yet called that) and Kim Cameron's work
, to no effect at all, at least in the Linux
community. It was like fishing for trout with handgun for bait.
... for the Identity Metasystem...
More confusion. What was the Identity Metasystem? Those who followed Kim and his
team knew (and said) that it was bigger than Microsoft. Kim says here
that the diverse needs of
many players demand that we weave a single identity fabric out of multiple constituenttechnologies. Many players, not just one. Not just Microsoft. At that same link, Kim's 5th

Law of Identity says, A universal identity system must channel and enable the inter-
working of multiple identity technologies run by multiple identity providers. Again, not
just Microsoft. But who knew that, outside folks that came to Internet Identity Workshops
or followed the topic closely? Not many, or at least not enough.
... CardSpace is an instance of a class of identity client software called an Identity
Selector...
Talk about burying the lead. The identity selector was THE big feature/virtue of Cardspace.
The world still needs it. U-Prove (Microsoft's new substitute) doesn't do it. Far as I know,
nothing else does.
... CardSpace stores references to users' digital identities for them, presenting them to
users as visual Information Cards...
Again, cards is good. informationcards isn't. Again a modifier problem. And a
metaphorical mess. They didn't want to say "identity cards," but that would have been
clearer for the user.
...CardSpace provides a consistent UI designed to help people to easily and securely use
these identities in applications and web sites where they are accepted...
Okay. But is it the UI or is it more than that? Also kinda blurry.
... Resistance to phishing attacks and adherence to Kim Cameron's "7 Laws of Identity"[1]
were goals in its design...
Nice virtues, but not top priority for users or developers.
Here's another reason: Microsoft never got behind it in a serious way. Great wind-up,
weak pitch. When other Information Card Foundation members wanted to move forwardwith development and evangelism, Microsoft was AWOL. From all I could tell (as an
outsider), they sandbagged it. Whatever the reason, Microsoft failed Cardspace. It wasn't
the other way around.

Microsoft, never strong in the Identity space, brought this out (against the developers'
wishes) with absolutely no go-to-market strategy. It didn't so much fail as wither because
there was no way for 3rd parties to make use of it.
