eIDAS 2.0 and the European Digital Identity Wallet
Public administrationAccepting a credential the citizen holds and you did not issue, and verifying it without calling the issuer for permission.
A citizen cannot switch to another tax authority. A patient in an emergency department cannot shop around. Both sectors serve people who have no alternative, under rules written by somebody else, on systems that are older than most of the staff using them.
In most industries identity is a design decision. Here it is largely a translation exercise: an obligation arrives, and something in the architecture has to answer it.
Accepting a credential the citizen holds and you did not issue, and verifying it without calling the issuer for permission.
Federating with a scheme you do not control, at the assurance level the service requires — and degrading gracefully for people who do not have one.
Multifactor authentication on systems in scope, access governance you can evidence, and incident timelines that assume you can answer who had access.
Purpose-bound access, consent that can be withdrawn, and a record of who read what — not only of who changed it.
Access tied to a current professional registration, which expires, is suspended, and is maintained by a body outside your organisation.
The citizen arrives holding a credential from a national scheme, a bank, or a wallet on their phone. Your job is to decide what it entitles them to — not to re-establish who they are.
Checking a bin collection date and filing a planning objection are not the same act. Binding the required assurance to the service, rather than to the portal, is what keeps low-stakes services usable.
Each body has its own mandate, its own legal basis and its own systems. Federation lets a citizen move between them without any agency handing over control of its register.
Every scheme has a population it does not reach. A service that only works for wallet holders excludes exactly the people most likely to depend on it, which is a design failure rather than an edge case.
Retention obligations measured in decades meet platforms replaced every seven years. Whatever proves who accessed what has to survive the tool that recorded it.
Everywhere else, denying uncertain access is the safe default. In a clinical setting it is not — which is why break-glass exists, and why it has to be designed rather than tolerated.
A patient who is not theirs, on a ward they do not normally cover, at three in the morning. Every second spent on identity is a second not spent on care.
The system does not queue an approval. It lets them in, immediately, because refusing is the outcome with the worst possible failure mode.
The event is recorded, flagged and routed to whoever reviews break-glass use, while the clinician is still on the ward.
The review is the control. It only works if the volume is small enough to be read, which means routine access must never need break-glass.
A shift covers several wards and a dozen shared terminals. Sign-in has to be seconds, repeatable, and must not tempt anybody into leaving a session open for the next person.
The right to see a record follows a professional registration held by an external body — one that expires and can be suspended. The entitlement has to follow it, not a copy of it made at onboarding.
In most systems the audit trail cares about changes. Here, who read a record is the question that matters, and it is asked long after the fact.
National schemes, wallets and verifiable credentials are nodes in the journey, so accepting a new one is a change to a diagram rather than a project inside every service.
Immediate access, with its own recording, its own notification and its own review — drawn explicitly, so what happens at three in the morning is a decision somebody made in advance.
Because each branch is versioned and each decision recorded, the answer to an auditor or a regulator is a report rather than a reconstruction.
These programmes almost always start from a regulation rather than an idea. Working from the deadline backwards is usually the honest way to plan them.
