How Basic Authentication Works
Encoding Process
The credentials are combined as username:password, then Base64-encoded. The result is sent in the Authorization header as Basic <token>.
Security Warning
Basic Auth only encodes credentials, it does NOT encrypt them. Always use HTTPS when sending Basic Auth headers to prevent credential exposure.
Common Use Cases
Basic Auth is commonly used with REST APIs, internal tools, reverse proxies (nginx), CI/CD pipelines, and testing environments.
