HTTP Basic Authentication Overview

  • Encoding vs Encryption: Basic authentication uses standard Base64 encoding (`username:password`), which provides no confidentiality by itself. Always pair Basic Auth with HTTPS / TLS in production.
  • Header Format: The authorization header takes the format `Authorization: Basic `.
  • Security Considerations: Restrict access to endpoints protected by Basic Auth and rotate credentials regularly to mitigate interception risks.
