The US already has all the necessary standards (OAuth 2.1, FAPI 2.0, DPoP, NIST SP 800-207, Zero Trust) — what's missing is a composed, published profile and governance discipline. The post maps German components to US equivalents: BundID becomes login.gov, MeinUnternehmenskonto becomes SAM.gov/UEI, BSI baseline becomes NIST RMF/SP 800-53, and protection tiers key to FIPS 199 impact levels. A six-step implementation sequence is proposed: publish a US Government API Authorization Profile v0.1, encode it as a Spectral ruleset for CI conformance, stand up an OPA-based decision point with AuthZEN, wire identity anchors, run a two-service pilot, and document decisions openly as ADRs. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What authentication and authorization standards does Germany's federal API authorization blueprint use that the US could adopt directly? Germany's blueprint combines OAuth 2.1, OpenID Connect, FAPI 2.0, DPoP for sender-constraining tokens, mutual TLS for internal control planes, private_key_jwt for client authentication, dynamic client registration with signed software statements, the NIST SP 800-162 attribute-based access model, and Zero Trust principles from NIST SP 800-207 and OMB M-22-09. All of these are already standard in American government technology, so the recommendation is to profile them rather than invent new schemes. _Track how governance teams turn API authorization standards into practical playbooks on daily.dev._ ### What US identity systems could replace Germany's BundID and MeinUnternehmenskonto for API authorization? login.gov, combined with agency identity providers and PIV/CAC credentials through the federal ICAM framework, could serve as the US equivalent of BundID for citizen identity. SAM.gov and the Unique Entity ID could serve as the organizational identity anchor in place of MeinUnternehmenskonto, with FICAM trust frameworks replacing eIDAS cross-border trust arrangements. _Developers mapping identity anchors across government systems can follow this comparison on daily.dev._ ### How can API authorization conformance be enforced automatically in government API pipelines? A published authorization profile's MUST and SHOULD requirements can be encoded as a Spectral ruleset that runs against an agency's OpenAPI definitions in CI, per protection tier, making conformance checkable on every commit rather than reviewed only once a year. Open Policy Agent can serve as the policy decision point, with OpenID AuthZEN providing a standard decision interface. _Teams building automated API governance checks can follow tooling patterns like this on daily.dev._ ## Similar posts on daily.dev - [Germany Built the API Authorization Blueprint the Rest of Government Needs](https://daily.dev/posts/germany-built-the-api-authorization-blueprint-the-rest-of-government-needs-6zyqh6i0w) · API Evangelist · 6 upvotes · 1 comments - [Profile, Don't Invent: How Germany Chose OAuth 2.1 and FAPI 2.0](https://daily.dev/posts/profile-don-t-invent-how-germany-chose-oauth-2-1-and-fapi-2-0-qoirligjb) · API Evangelist · 1 upvotes · 0 comments - [A Playbook for Europe: eIDAS, Sovereignty, and a Shared GovTech Ecosystem](https://daily.dev/posts/a-playbook-for-europe-eidas-sovereignty-and-a-shared-govtech-ecosystem-iipiflfhd) · API Evangelist · 0 upvotes · 0 comments - [Common FAPI Misconceptions](https://daily.dev/posts/common-fapi-misconceptions-qpx9ntthq) · Auth0 · 1 upvotes · 0 comments - [Who Decides?
