About Basic Authentication

HTTP Basic Authentication is a simple authentication scheme built into the HTTP protocol. The client sends HTTP requests with an Authorization header that contains the word "Basic" followed by a space and a base64-encoded string of "username:password".

While simple to implement, Basic Auth is not secure over unencrypted HTTP connections as the credentials can be easily intercepted. It should always be used over HTTPS. This tool performs the base64 encoding locally in your browser.
