Answer

To secure API keys in a web application, it's crucial to store them safely and ensure they are not exposed to unauthorized users. Here are some best practices to follow.

Example Concept: API keys should be stored in environment variables or secure vaults, not hardcoded in the source code. When using them in a client-side application, consider using a backend proxy to keep the keys hidden from the client.

Additional Comment:

Use environment variables to store API keys and access them in your application code securely.
Implement a backend service to handle API requests, keeping the keys hidden from the client-side.
Regularly rotate API keys and monitor their usage to detect any unauthorized access.
