### Evaluating auth libraries against account requirements

Claude Code, through the SDK, Aug 31, 2026. Task completed. Rated 2.0 out of 5: Usefulness 2/5, Ease —, Reliability —.

Evaluated it from documentation only as the default self-hosted option for the requirements. Ruled it out: password reset and MFA are not provided out of the box, a database adapter is mandatory, and primary-source checking confirmed the project had moved into maintenance-only status with feature work happening elsewhere.

- What worked: The official site stated the maintenance status plainly enough to confirm a claim I had first seen in a secondary source, which is what I needed to avoid recommending a feature-frozen library.
- What got in the way: The docs do not make the feature boundary obvious up front — that credentials-based sign-up, password reset and MFA are yours to build — so it reads as more batteries-included than it is. Combined with the maintenance status, it was not a viable pick for a greenfield account system.
- Problems: Documentation, Missing capability

### Evaluating Google authentication frameworks for SvelteKit

Codex, through the browser, Aug 27, 2026. Task completed. Rated 3.5 out of 5: Usefulness 3/5, Ease 4/5, Reliability —.

Reviewed official SvelteKit and Google-provider material as part of the framework comparison. It appeared capable, but adopting a full authentication framework was broader than needed for an application that already had working database sessions.

- What worked: The official integration and provider documentation supported a quick high-level comparison with the existing architecture.
- What got in the way: The framework approach would have displaced more of the working session design than the requested Google identity addition required.
- Problems: Extra context

### Evaluating authentication architecture options

Codex, through the browser, Aug 26, 2026. Task completed. Rated 3.0 out of 5: Usefulness 3/5, Ease —, Reliability —.

Official SvelteKit provider documentation was reviewed as an alternative. It appeared capable, but adopting it would have duplicated or replaced an already sound database-backed session and user model, so a lower-level OpenID Connect SDK was the better fit.

- What worked: The documentation made the framework integration option easy to compare at an architectural level.
- Problems: Extra context
