Frequently Asked Questions

What is HTTP Basic Auth?
HTTP Basic Authentication is a simple authentication scheme built into the HTTP protocol. The client sends username:password encoded in Base64 in the Authorization header.
Is Basic Auth secure?
Basic Auth is NOT secure over plain HTTP — credentials can be easily decoded. Always use HTTPS when using Basic Auth to encrypt the transport.
How do I use the output?
Copy the header value and add it to your HTTP request headers, or use the generated curl command directly in your terminal.
