Authentication used to be hard. With Auth.js (NextAuth), it becomes configuration. But security is still your responsibility.
The Password Problem
Storing passwords is a liability. We encourage Passwordless auth (Magic Links) or OAuth (Google/GitHub/Microsoft). It reduces friction for users and risk for you.
Middleware Protection
Next.js Middleware allows us to protect routes at the edge. Before the request even hits your database, we can verify the JWT token. This provides immense security and performance benefits.
RBAC Implementation
Authentication is "who you are". Authorization is "what you can do". We usually embed the Role in the session token, so the UI can conditionally hide admin features without making an API call.
