To securely implement social login in Angular applications, follow these steps:
1. Choose a library: Select an authentication library like AngularFireAuth or Auth0 to handle the process.
2. Configure providers: Set up Google and Facebook as authentication providers by creating developer accounts and obtaining API keys.
3. Integrate with Angular: Import the chosen library into your Angular application and configure it with the obtained API keys.
4. Create UI components: Design login buttons for each provider and bind them to corresponding methods that trigger the authentication process.
5. Handle authentication response: Upon successful authentication, store user information (e.g., access token) in a secure manner, such as HttpOnly cookies or localStorage.
6. Protect routes: Use route guards to restrict access to specific parts of the application based on user’s authentication status and roles.
7. Implement logout functionality: Provide users with a way to log out, clearing stored tokens and revoking permissions granted during the login process.
