Next.js Authentication Feature Build

My current Next.js code-base is running smoothly, but it still needs a full user-account flow. I want to add: • Email-and-password sign-up and login, including secure password hashing and session handling (NextAuth, bcrypt, or a comparable library are fine—feel free to suggest the best fit)...
