Security Warnings

  • Always use HTTPS when sending Basic Auth headers - HTTP sends credentials in plain text
  • Basic Auth credentials are encoded, not encrypted - Base64 can be easily decoded
  • Consider using API keys, OAuth, or JWT for production applications
  • Never commit credentials to version control
  • Rotate credentials regularly
  • Use environment variables to store sensitive data
