HTTP Basic Auth
Build or parse an Authorization: Basic header from a username and password.
How it works
Enter username and password
Type both in the fields. The header updates as you type. Or paste a header and decode.
Decode the header
Decode fills username and password from a pasted Authorization: Basic header or a raw Base64 token.
Copy the field you need
Copy sits on each field label: username, password, or the full header.
What is HTTP Basic Auth?
HTTP Basic Authentication puts a username and password into an Authorization header as Base64 of user:password. APIs and older servers still ask for it. This page builds that header or reads one back in the tab. Easy24 does not receive what you type.
Why use this tool
- HTTP Basic Auth runs in a browser tab.
- Header updates as you type. Decode a pasted header
- Show or hide the password. Copy sits on each field label

It builds or reads an Authorization: Basic header. The header is Base64 of username:password. This page runs in your browser.
How do I use it?

Why is the password visible?
It is hidden by default. Use the eye to show it. This is a local encoder, not a login form. Do not screenshot the page if the password is real.
Is Basic Auth encryption?
No. It is Base64 encoding. Anyone who sees the header can read the password. Use it only over HTTPS.
