Authentication & Authorization

What this module covers

5 steps · Next.js

1. Step 1. Lesson: Authentication & Authorization

   Implement sessions, protected routes, server-side authorization, ownership checks, and secure account flows. Learning objectives - Recognize when authentication & authorization is the right tool. - Explain the role of session, authorize, server. - Build a small working example before combining it with a larger interface. - Identify one accessibility, maintainability, or error-handling improvement. Read the example, predict what it will do, then complete the small change described in the check question.

   Implement sessions, protected routes, server-side authorization, ownership checks, and secure account flows. In Next.js, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [Next.js] Use the example to demonstrate authentication & authorization.

2. Step 2. Quiz: Authentication & Authorization

   Check your understanding of Authentication & Authorization.

   Client UI is not a security boundary; the server must verify every protected operation. In Next.js, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [Next.js] Complete the knowledge check.

3. Step 3. Exercise: Authentication & Authorization

   Protect a dashboard and enforce resource ownership inside the server mutation itself.

   This exercise turns the Authentication & Authorization lesson into a working code change. In Next.js, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [Next.js] Does the solution use session and authorize and server?

4. Step 4. Review lab: Explain & improve Authentication & Authorization

   Rebuild the exercise without copying the solution. Then improve it in two ways: make the code easier to understand and add one useful edge case, responsive behavior, accessibility improvement, or error state. Finally, write a short explanation of how session, authorize, server work together.

   Rebuilding from memory and improving an edge case turns recognition into durable skill. In Next.js, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [Next.js] Does the improved version still use session, authorize, server clearly?

5. Step 5. Mini project: Authentication & Authorization

   Build signup, login, logout, protected navigation, role checks, ownership checks, and secure recovery boundaries.

   The mini project combines the module lesson, quiz, and exercise into one portfolio-ready result. In Next.js, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [Next.js] Does the project apply the module's authentication & authorization skills?
