Teams should start by framing the challenge around a specific use case, then provide a clear path to build, test, and submit a working project. Good documentation, accessible support, and realistic problem statements matter because they reduce friction and help contributors focus on solving meaningful authentication or secrets management problems rather than deciphering the event itself.
Start with a concrete authentication or secrets problem
The first priority is to narrow the challenge to one realistic use case, such as passwordless login for a developer tool, secure API key handling in CI/CD, or rotating a sensitive secret without breaking a build. That focus keeps teams solving an authentic engineering problem instead of designing for a vague ideal. A good challenge statement should make the security outcome, user path, and expected deliverable obvious from the start.
For passwordless authentication, that usually means defining the exact trust boundary, for example how a user proves possession, how the session is issued, and what happens when the credential is lost or replayed. For secrets management, it means specifying where secrets originate, where they are stored, and how they are retrieved or revoked. Teams move faster when the challenge makes those decision points explicit.
Use cases grounded in the real failure modes of identity and secrets handling work best because they naturally point teams toward meaningful design choices. If the challenge is too broad, participants may spend most of their time debating architecture instead of building something testable. If it is too narrow, they may only reproduce a known pattern without showing judgment. The sweet spot is a scoped problem with enough room for design trade-offs.
Make the build and test path frictionless
Once the use case is set, the next priority is a clear path from idea to submission. Teams should know what to build, how to test it, how to package it, and how success will be judged. Challenge organisers often underestimate how much momentum is lost when setup instructions, local prerequisites, or submission rules are ambiguous. Good documentation is not decoration here, it is part of the challenge design.
Accessible support matters for the same reason. If participants cannot quickly confirm whether a failure is caused by their implementation or by the event setup, they will spend their energy debugging the challenge rather than the solution. A well-run challenge provides starter material, sample inputs, and a reproducible environment so teams can validate progress early. That is especially important when the subject involves authentication flows or secret-handling logic, where small configuration mistakes can block the entire project.
Realistic problem statements also help teams prioritise correctly. The challenge should reflect how passwordless authentication or secret management behaves in practice, including state transitions, error handling, and operational constraints. The goal is not to hide the hard parts, but to make sure the hard parts are the right ones. That keeps the event educational and keeps submissions comparable.
Risk and Threat Considerations
Passwordless and secrets-management challenges can fail if they reward demos that ignore abuse paths, weak recovery logic, or unsafe secret exposure. Teams should prioritise designs that reduce standing secrets, minimise long-lived credentials, and make misuse observable rather than hidden. In this space, a polished flow that cannot be revoked, audited, or rotated is usually a weak design even if it looks elegant in a demo.
Failure mechanism: Overly permissive credentials, hardcoded secrets, or poorly designed recovery paths create a straightforward compromise path, especially when developers reuse the same pattern across multiple services or environments.
Impact: A successful compromise can expose API access, break trust in the authentication flow, or turn a challenge artifact into a real operational risk if it is copied into production-like systems.
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 and OWASP Agentic AI Top 10 address the attack and risk surface, while CIS Controls v8 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 — Secrets and Credential Management | Passwordless and secrets handling both depend on secure credential and secret control. |
| NHI-03 — Access Governance and Least Privilege | Challenge design should constrain trust boundaries and avoid overbroad access paths. | |
| NHI-08 — Lifecycle and Rotation | Secret handling challenges should test rotation, expiry, and revocation behavior. | |
| Recommendation — Enforce secure secret storage, rotation, and revocation for challenge scenarios. Limit challenge credentials and permissions to the minimum required for the use case. Design submissions to prove rotation and revocation workflows work end to end. | ||
| OWASP Agentic AI Top 10 | A1 — Identity and Access Control | Passwordless flows need explicit authentication and session trust decisions. |
| Recommendation — Specify how users authenticate and how sessions are issued and recovered. | ||
| CIS Controls v8 | 6 — Access Control Management | The challenge centres on managing access paths and reducing exposure. |
| 16 — Application Software Security | Teams need clear build and test guidance for secure implementation work. | |
| Recommendation — Restrict access paths and review credentials used in the challenge environment. Provide reproducible build and test instructions for the challenge. | ||
| NIST CSF 2.0 | PR.AC — Access Control | The subject is about establishing and constraining access in a challenge context. |
| PR.AT — Awareness and Training | Good documentation and support improve participant understanding and execution. | |
| Recommendation — Define and enforce least-privilege access for challenge resources. Publish clear instructions so teams can complete the challenge without ambiguity. | ||
Practitioner Guidance
What to prioritise: Start by defining the one workflow the challenge is meant to improve, then write the acceptance criteria around that workflow instead of around technology novelty. For passwordless authentication, verify the login and recovery path are both testable; for secrets management, verify rotation or retrieval can be demonstrated without leaking material into code or logs.
What to verify: Teams should be able to show a working end-to-end path, not just a diagram. That means checking that the submission can be built from the provided instructions, exercised in a realistic environment, and explained in terms of how it handles trust, exposure, and failure.
Practitioner takeaway: The best developer challenges make the security decision points visible, because once the use case is clear, teams can spend their effort on solving the real authentication or secret-handling problem rather than reverse-engineering the event.
