Basic Auth Header Guide

About this tool

Build the Authorization: Basic header value from a username and password, and optionally produce a ready-to-use curl command. The encoding is plain Base64, which is exactly why it is only safe over HTTPS.

Questions

Is Basic authentication encrypted?
No. The credentials are Base64-encoded, which anyone can reverse. They are protected only by the TLS connection carrying them, so never use it over plain HTTP.
