HTTP Basic Auth Header Generator
Runs 100% in your browser — your files never leave your device.
Testing a protected endpoint often requires the exact Authorization: Basic header rather than separate credentials. Enter a username and password to produce the UTF-8-safe base64 header, then copy it into curl, Postman, or an API client.
How it works
- 1
Enter the username
- 2
Enter the password
- 3
Copy the Authorization header
