Authentication Functions, UI, and Protected Routes

Authentication Functions, UI, and Protected Routes

In this section, you will integrate AWS Cognito into your Next.js application using the Amplify SDK.
You will implement core authentication logic, build a user-friendly UI, and secure specific pages using protected routes.

By the end of this section, your application will support:

✔ Features You Will Implement

• Sign Up Function
  Create new users in Cognito (with email verification).

• Sign In Function
  Authenticate users and receive Cognito-issued tokens.

• Sign Out Function
  Properly terminate the authenticated session through Amplify.

• Session Handling
  Check whether users are logged in and retrieve current session info.

• Protected Routes
  Restrict access to certain pages unless the user is authenticated.

• UI Components
  Build simple authentication pages such as Login, Register, Profile, and Dashboard using your chosen UI library.
