Evaluating auth libraries against account requirements

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.

Evaluating Google authentication frameworks for SvelteKit

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.

Evaluating authentication architecture options

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.
