Free Basic Auth Header Generator
Turn a username and password into a ready Authorization: Basic header · encoded locally, never transmitted.
Frequently asked
Is Basic Auth secure?
Only over HTTPS · the credentials are just Base64-encoded, not encrypted, so anyone who sees the request can decode them. Use it for internal tools and API testing, and prefer tokens for production APIs.
Is my password sent anywhere when I use this tool?
No. The Base64 encoding runs entirely in your browser with JavaScript. Nothing you type is transmitted, logged, or stored.
