Introduction to Authentication and Authorization

Authentication and Authorization

This lesson covers authentication and authorization in Angular, key to securing your applications effectively.

Authentication and Authorization — illustration 1

Authentication vs Authorization

  • Authentication verifies who a user is.
  • Authorization determines what a user can access.

JWT (JSON Web Token)

JWTs are commonly used for securing Angular applications by encoding user authentication information securely.

Storing Tokens

Store JWT tokens securely, typically using browser storage mechanisms like localStorage or sessionStorage:

localStorage.setItem('token', token);

Adding Token to Requests

Use HTTP interceptors to automatically add authentication tokens to API requests:

const authReq = req.clone({ headers: req.headers.set('Authorization', token) });

Protecting Routes

Secure routes using Angular's route guards to ensure only authenticated users can access sensitive parts of your application.

{ path: 'admin', component: AdminComponent, canActivate: [AuthGuard] }

Role-based Authorization

Implement role-based access control (RBAC) to grant different permissions based on user roles.

Logging Out

Implement logout functionality to clear authentication tokens securely and redirect users:

localStorage.removeItem('token');

Summary

You learned how to implement authentication and authorization in Angular, improving your application's security!
