Authentication, Authorisation & Trust

What should providers do if patients cannot complete photo-ID verification?

← Back to all FAQ
By NHI Mgmt Group Editorial Team Updated October 27, 2026 Domain: Authentication, Authorisation & Trust

Build an alternative route that still supports legitimate access, such as a trusted registration-based method or another approved fallback. Otherwise the service turns identity proofing into an exclusion point and blocks patients who can use the service safely but cannot produce standard photo ID.

Why an Alternative Route Is the Right Design Choice

The issue is not whether photo ID is useful. It is whether a single proofing path is being treated as the only legitimate path to care or service access. When that happens, identity verification becomes a gate that can exclude otherwise valid patients. A safer design is to separate “can we verify this person with acceptable confidence?” from “must this person have this exact document type?”

An alternative route should preserve the same assurance goal while changing the evidence used to reach it. That might mean a trusted registration-based method, a known-patient workflow, or another approved fallback that is proportionate to the service being accessed. The key is that the fallback is pre-defined, reviewable, and operationally available before someone gets stuck at the front door.

Where a provider offers multiple proofing paths, the stronger control is not the most rigid one, but the one that still works for legitimate users with different document situations. This is especially important when the proofing step is tied to enrolment, appointment access, prescription access, or patient portal access, because the service failure then becomes a care-access problem, not just an admin problem. Identity Verification Buyer's Guide is useful here because it frames vendor choice around document checks, liveness, coverage, accuracy, and fallback considerations.

What Makes a Fallback Legitimate Rather Than a Loophole

A legitimate fallback still needs to answer the same underlying question: is this person the one who should receive access? The method can change, but the assurance standard should not collapse. Providers should define which fallback methods are acceptable, who can approve them, what evidence is required, and when a manual review is needed.

The most common failure is designing a workaround that is informal, ad hoc, or dependent on one staff member’s judgement. That creates inconsistency and increases the chance that either legitimate patients are rejected or impostors are waved through. A better pattern is a controlled alternate route with clear eligibility rules, documented evidence, and a repeatable decision path.

If the service already has a patient record, prior registration, insurer data, referral evidence, or another trusted relationship, those signals can be used to support access without insisting on photo ID as the sole proof. The important distinction is that the fallback must be strong enough for the use case, not merely convenient for operations.

For teams building the verification flow itself, the security baseline is about authentication quality, session handling, and access decisions. OWASP ASVS is relevant because it anchors those decisions in authentication, session, and access-control requirements rather than in a single document type.

How Providers Should Operationalise the Exception Path

The practical task is to make the exception path predictable. Staff should know when to offer it, what evidence to collect, how to record the reason for using it, and when to escalate for manual review. If a provider cannot describe that process in one short operating procedure, the fallback is probably too vague to rely on.

Providers should also test the path from the patient’s perspective. A fallback is only effective if it is actually usable by the people who need it, including patients who lack standard ID, have changed names, are recovering from loss or theft, or face other barriers to document presentation. The right question is not “does the policy exist?” but “can a legitimate patient complete it without being trapped in repeated exceptions?”

Where regulation, privacy, or clinical workflow makes a specific verification method harder to use, the answer is still not to remove access. It is to choose a different approved path that preserves safety and accountability. For digital identity design, the core control question is whether the assurance level fits the action being taken, not whether a single artifact was produced.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

OWASP ASVS and NIST SP 800-63 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.

FrameworkControl / ReferenceRelevance
OWASP ASVSV6 — AuthenticationFallback ID verification still must establish acceptable assurance for access.
Recommendation — Define authentication requirements that allow approved alternate proofing paths.
NIST SP 800-63Digital Identity GuidelinesThe question is about choosing an assurance-appropriate fallback for identity proofing.
Recommendation — Align fallback proofing to the assurance level needed for the service.
ISO/IEC 27001:2022A.5.15 — Access controlProviders need a controlled access decision when the primary proofing method fails.
Recommendation — Document alternate access rules and apply them consistently.

Practitioner Guidance

What to prioritise: define the fallback before rollout, not after the first denied patient. A good exception path is a policy, a workflow, and a training item, not an improvised staff judgement.

What to verify: confirm that the alternate route still distinguishes genuine patients from unsupported claims of identity, and that staff can complete it consistently without escalating every case to a supervisor.

Common mistake: treating photo ID as the only acceptable proofing method even when the service could safely support a different trusted route. That turns a control into an access barrier.

Practitioner takeaway: the best design is not “no exceptions”, it is a controlled alternative that preserves assurance while preventing legitimate patients from being excluded by one narrow proofing method.
