What are the security considerations for OAuth 2.0 Authorization Code Flow?

The OAuth 2.0 Authorization Code Flow has several security considerations, including the need for secure storage of client secrets, the use of HTTPS to prevent man-in-the-middle attacks, and the importance of validating redirect URIs to avoid open redirect vulnerabilities.

How can I ensure the client secret is stored securely?

You should store the client secret in a secure environment, such as a server-side application, and avoid hardcoding it in your client-side code. Using environment variables or secure vaults can help protect it.

What are the risks of using HTTP instead of HTTPS?

Using HTTP exposes your application to various risks, including eavesdropping, man-in-the-middle attacks, and data tampering. Always use HTTPS to encrypt data in transit.

Can you explain the importance of validating redirect URIs?

Validating redirect URIs is crucial to prevent open redirect vulnerabilities, where attackers can redirect users to malicious sites. Always ensure that the redirect URI matches the registered URI for your application.
