Integrate Singpass (citizen/resident login and Myinfo (v5) government-verified person data) into a Singapore government digital service using the current FAPI 2.0 Singpass authentication API. Use this whenever a service authenticates individual members of the public or pre-fills their personal data: "log in with Singpass", Singpass Login, Myinfo, NRIC/UUID identity, PAR, DPoP, userinfo, the Singpass Developer Portal (SDP), consent pages, Myinfo scopes (uinfin, name, CPF, NOA, HDB), test…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Singpass: citizen login and Myinfo (v5) on FAPI 2.0

Singpass is Singapore's national digital identity: an OpenID Connect provider that
supports the authorization-code flow only, and relying parties must be confidential
clients. Two products share one API and one onboarding portal:

- **Singpass Login** — authentication only. The flow ends at the ID token.
- **Singpass Myinfo (v5)** — Login plus consented retrieval of government-verified
  person data from the `/userinfo` endpoint. Every Singpass user automatically has a
  Myinfo profile.

The current API is **fully OIDC + FAPI 2.0 compliant** (new apps are FAPI 2.0 by
default since Feb 2026; **all Singpass APIs must be FAPI 2.0-compliant by
31 Dec 2026**). Use a **certified OIDC relying-party library** (openid.net certified
list) rather than hand-rolling. Singpass says so explicitly, and the library handles
PAR, PKCE, DPoP, and claim validation correctly. If you are maintaining a
Myinfo v3/v4 integration or a pre-FAPI Login flow, read **sg-gov-singpass-legacy**; it
covers the different endpoints, crypto, and hard deadlines.

How to install

The exact contents, by fingerprint

mdr add kyleoliveiro/sg-gov-skills/sg-gov-singpass@sha256:a0fa852c10f3f692

The line at the top of this page pins the label git:20261027.6f21efa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
