How calladitya/authentication-system works

This is an Express authentication API. Requests enter through the server and auth routes, then the controller handles registration, login, profile lookup, session refresh/logout, and OTP verification using MongoDB models and email/OTP helpers. The README describes protected routes, but the sampled routes show no authorization middleware, so none is represented. Controller excerpts are partial; links among its workflows and storage are limited to relationships visible in those excerpts or the source index.
