Authentication
The process of verifying the identity of a user, device, or system attempting to access a resource.
In-Depth Explanation
Authentication verifies identity - confirming you are who you claim to be. In API and system integration contexts, authentication ensures only authorized entities can access services.
Authentication methods:
- API keys: Simple tokens for service identification
- OAuth 2.0: Delegated authorization with tokens
- JWT: Self-contained tokens with claims
- Mutual TLS: Certificate-based authentication
- Basic auth: Username/password (legacy, avoid)
Authentication factors:
- Something you know (password, PIN)
- Something you have (token, phone, certificate)
- Something you are (biometrics)
Multi-factor authentication (MFA):
- Combines multiple factors
- Significantly increases security
- Required for sensitive systems
API authentication flow:
- Client provides credentials
- Server validates credentials
- Server issues token/session
- Client includes token in subsequent requests
Business Context
Proper authentication prevents unauthorized access to systems and data. For US businesses, it's the foundation of API security and compliance with SOC 2, HIPAA, and state privacy laws.
