Lean OAuth 2.0

The request hits your desk: integrate OAuth 2.0 without the bloat. No sprawling codebases. No complex identity infrastructure. Just fast, clean authentication that works. That’s the promise of Lean OAuth 2.0.

Lean OAuth 2.0 strips the protocol down to the essentials. Authorization Code flow with PKCE. Direct, minimal configuration. Strong security without carrying the weight of every possible extension or grant type. It focuses on what you actually use—access tokens, refresh tokens, and scopes—while cutting out unused flows that slow teams down.

With Lean OAuth 2.0, the token lifecycle stays predictable. Access tokens are short-lived for security; refresh tokens only persist as long as needed; scope definitions are explicit and easy to audit. Every step of the handshake is transparent, letting developers see exactly how the client, authorization server, and resource server interact.

The result is faster onboarding. New services connect through OAuth 2.0 without weeks of trial-and-error. Documentation stays short. Security reviews run faster. Maintenance is simpler because there’s less surface area to secure. Lean OAuth 2.0 is especially effective for microservices and serverless environments, where minimizing dependencies reduces both risk and latency.

You don’t lose compliance or standards alignment. The flows are still RFC 6749-compliant, tokens still follow JSON Web Token (JWT) or opaque token best practices, and encryption is still handled with stable, well-supported libraries. But every piece is intentional.

Lean OAuth 2.0 isn’t about rethinking the protocol—it’s about executing it cleanly. It’s for teams that want the security model without the ecosystem sprawl.
