Overview

API authentication is a critical component of any secure application. This guide will walk you through the basics of implementing authentication in your API.

Authentication Methods

There are several common methods for API authentication:

• API Keys: Simple token-based authentication
• OAuth 2.0: Industry-standard authorization framework
• JWT Tokens: JSON Web Tokens for stateless authentication
• Basic Auth: Username and password credentials

Best Practices

1. Always use HTTPS for API requests
2. Never expose API keys in client-side code
3. Implement rate limiting to prevent abuse
4. Rotate credentials regularly

Next Steps

Once you’ve implemented basic authentication, you can explore more advanced topics like token refresh mechanisms and multi-factor authentication.
