Integration overview
FastLogin is a standards-based OAuth2 / OpenID Connect identity provider. If you've integrated "Sign in with Google" or an enterprise SSO (Okta, Auth0), the shape of integration is identical: you register your application, redirect users to FastLogin to sign in, and receive an ID token on the callback.
What you can integrate with today
- Sign in with FastLogin — standard OAuth2 authorisation-code flow with PKCE.
- Single sign-out — standard OpenID Connect RP-initiated logout.
- MFA-required sign-in — request a step-up if your product needs a higher assurance for a specific action.
- Verified-provider claims — receive verified-provider status (e.g. "this user is a licensed doctor") in the ID token so your product can gate features on it.
- Organisation membership claims — receive a user's organisation and role in the ID token.
Standards & protocols
- OAuth 2.0 authorisation-code flow with PKCE for public clients.
- OpenID Connect 1.0 for identity claims.
- WebAuthn / passkeys for the strongest MFA factors.
- Standard key discovery — your application validates ID-token signatures using FastLogin's published public keys, no shared secrets.
- NDPA 2023 data-subject-access-request (DSAR) workflows for export, rectification, and erasure, surfaced through FastLogin so partners don't have to implement them separately.
Get in touch
We're onboarding integration partners deliberately. If you're building a healthcare product that would benefit from Fastclinic identity, or a service that would let Fastclinic users sign in with their FastLogin account, reach out and we'll share integration details.
