Previous Question Next Question

To secure API keys in a web application, it's essential to keep them confidential and manage their access carefully. Here’s a structured approach to doing so:

Example Concept: API keys should be stored securely and never hardcoded in client-side code. Use environment variables or secure vaults to manage them. Ensure that API keys have the least privilege necessary and are rotated regularly to minimize risk in case of exposure.

Additional Comment:

Store API keys in environment variables or a secure vault, not in the codebase.
Use server-side code to interact with APIs, keeping keys hidden from the client-side.
Regularly rotate API keys and monitor their usage for unauthorized access.
