The Digital Credentials API is a browser interface that lets websites request verifiable credentials from compatible wallets. It standardises presentation across wallets and protocols, so identity teams can think in terms of claims and verification outcomes rather than custom app-to-app handoffs.
Expanded Definition
The Digital Credentials API is the browser layer that lets a website request a verifiable credential from a supported wallet and receive a presentation that can be checked for integrity, issuer trust, and claim relevance. It sits at the intersection of web UX, wallet interoperability, and identity assurance, and it is still an evolving area where implementation details vary across platforms and wallet ecosystems.
For NHI and IAM teams, the key distinction is that the browser mediates the request, but it does not replace the underlying trust model. Teams still need to understand what claims are being presented, what proof is attached, and how the verifier binds the response to a transaction. That places the Digital Credentials API closer to an assurance transport layer than a full identity system, similar in governance importance to the identity assurance concepts in NIST SP 800-63 Digital Identity Guidelines.
The most common misapplication is treating the API as proof of trust by itself, which occurs when a team accepts any wallet-delivered response without validating issuer policy, audience, freshness, and revocation conditions.
Examples and Use Cases
Implementing the Digital Credentials API rigorously often introduces policy and compatibility constraints, requiring organisations to weigh simpler user journeys against stricter verification rules and wallet support variance.
- A customer portal requests a reusable employment or membership credential, then verifies the response before granting access to a restricted workflow.
- An enterprise onboarding flow accepts a credential from a wallet instead of forcing repeated document uploads, reducing friction while preserving verification traceability.
- A regulated service uses the browser-mediated presentation to confirm attributes such as age, jurisdiction, or role, then maps those claims into an authorization decision.
- An identity team pairs browser-side presentation with policy checks informed by the OWASP Non-Human Identity Top 10 when credentialed automation or agents must prove who or what is acting.
- Security architects use the pattern alongside lessons from the Ultimate Guide to NHIs — Static vs Dynamic Secrets to reduce reliance on long-lived secrets in adjacent workflows.
In practice, the API is most useful when the verifier can decide quickly and the wallet can present only the minimum necessary claims. That makes it attractive for selective disclosure, but it also means policy design has to be explicit before deployment.
Why It Matters in NHI Security
For NHI security, the Digital Credentials API matters because it can reduce secret sprawl, shorten trust chains, and support more deliberate claim-based access decisions. Those benefits are valuable in environments where static credentials and app-to-app handoffs have historically produced leakage risk. NHIMG research shows that 23.7% of organisations still share secrets through insecure methods such as email or messaging applications, and 88.5% say their non-human IAM practices lag behind or merely match human IAM maturity, a sign that credential handling remains a governance gap rather than a solved problem.
Used well, the API can support stronger assurance for both human and agentic workflows, especially when combined with verifier policy, revocation checks, and a clear mapping from presented claims to access decisions. Used poorly, it can create a false sense of security if teams assume the browser or wallet has already validated trust. The governance lesson aligns with broader control expectations in NIST SP 800-53 Rev 5 Security and Privacy Controls, where authentication, authorization, and lifecycle discipline remain mandatory regardless of interface.
Organisations typically encounter the operational cost of this term only after a compromised credential, broken verifier assumption, or failed wallet integration disrupts access, at which point the Digital Credentials API becomes unavoidable to address.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST SP 800-63, NIST CSF 2.0, NIST Zero Trust (SP 800-207) and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital credentials depend on identity assurance, binding, and verifier trust rules. | |
| NIST CSF 2.0 | PR.AC-1 | Access is granted only after identities and credentials are validated. |
| OWASP Non-Human Identity Top 10 | NHI-02 | Credential handling risks align with secret and token misuse patterns in NHI systems. |
| NIST Zero Trust (SP 800-207) | Zero trust requires continuous verification of every credentialed transaction. | |
| NIST AI RMF | Agentic and automated identity decisions need governed, risk-based claim usage. |
Require verified issuer, audience, and freshness checks before accepting any credential presentation.
