JWT Authentication
JWT authentication uses signed tokens to let clients prove identity to an API without storing session state directly in the HTTP layer.
Where it fits
It is common in SPA-oriented stacks where a browser client talks to a backend API and needs an explicit bearer token for authenticated requests.
Repeated project patterns
- Status Alganize uses JWT-based auth in a standard dashboard flow.
- Study Duel uses JWT for API access and also passes authenticated context into websocket flows.
- In a FastAPI stack, JWT typically sits alongside typed login models, password hashing, and route-level dependency checks.
Trade-offs
- Token-based auth is flexible, but refresh, revocation, storage, and websocket handoff all need deliberate handling.
- Simplicity at the HTTP layer can hide security complexity elsewhere.
