API Authentication

Authentication is a critical aspect of API security. It ensures that only authorized users can access certain resources. There are several methods of authentication commonly used in APIs.

Common Authentication Methods

• API Keys: Simple tokens that are passed with requests.
• OAuth: A more secure method that allows users to grant access without sharing credentials.
• JWT (JSON Web Tokens): Compact tokens that can be used for authentication and information exchange.

Choosing the right authentication method depends on the specific use case and security requirements.
