How do OAuth redirects work in MVC applications?

In MVC applications, OAuth redirects are used to authenticate users via third-party services. When a user tries to log in, they are redirected to the OAuth provider's login page. After successful authentication, the provider redirects them back to your application with an authorization code.

What happens after the authorization code is received?

Once your application receives the authorization code, it exchanges it for an access token by making a request to the OAuth provider's token endpoint. This access token allows your application to make authorized API calls on behalf of the user.

Can you explain the security implications of using OAuth?

Certainly! OAuth helps protect user credentials by allowing them to authenticate without sharing their passwords. However, it's crucial to implement it correctly to avoid vulnerabilities like token leakage or improper redirect URIs.

What are some common mistakes to avoid when implementing OAuth?

Common mistakes include not validating redirect URIs, failing to use HTTPS, and not properly handling token expiration. Always ensure your implementation follows best practices.
