Basic Auth Generator

Build an HTTP Basic Authentication header — computed entirely in your browser

These never leave your device

About this tool

Generate an HTTP Basic Authentication header from a username and password. Produces the Authorization header and ready-to-use curl and fetch snippets. Runs fully client-side. Basic Auth Generator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • Basic Auth Generator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
