API authentication is essential when backend services are consumed by mobile apps, frontends, or third-party systems.
Laravel applications can use token-based authentication to verify clients and control access to protected endpoints.
Security Considerations
- Use HTTPS in production.
- Protect tokens and secrets.
- Apply expiration and revocation strategies where appropriate.
- Validate every request.
- Return safe and consistent error responses.
Authentication should always be combined with authorization so that authenticated users only access resources they are allowed to use.
