Basic Auth Header Generator — free online
You're testing an API or setting up a quick request, and it needs a Basic Auth header. So now you have to take a username and a password, glue them together, encode the result the right way, and hope you didn't fumble a character. It's a small, fiddly task that's easy to get wrong. We added a free tool that does it for you — Basic Auth Generator — right in your browser.
What it does
You type in a username and a password, and it gives you back the full HTTP Basic Auth header. You get the complete Authorization: Basic … line, ready to paste into your request, your terminal, or your API client.
Nothing leaves your device
This runs entirely in your browser. Your username and password are never uploaded, never sent anywhere, and nothing is saved after you close the page. The whole thing happens on your own machine, which matters when you're handling login details.
How to use it
- Open Basic Auth Generator and type in your username and password.
- The header is built for you straight away.
- Copy the full
Authorization: Basic …line and paste it where you need it.
It's free with no limit. There are more small tools on the Apps page.
