Basic Auth Header Generator

HTTP Basic Auth sends credentials in an Authorization header using the format Basic base64(username:password). It is common in quick API tests, internal dashboards, legacy systems, staging environments, and webhook endpoints protected by simple credentials.

This tool builds the header value from a username and password so you can paste it into an API client, curl command, proxy config, or request playground. Basic Auth is encoding, not encryption. Always use HTTPS so the header is protected in transit.

Use this generator for testing and documentation. For production systems, consider stronger authentication such as OAuth, signed requests, short-lived tokens, or mTLS when appropriate.
