About this tool

Basic Auth Generator converts username and password into a valid HTTP Basic token and ready-to-use Authorization header. It also provides a cURL example for quick API smoke tests. This is useful when checking staging endpoints, reverse proxy auth, or legacy integrations that still rely on Basic authentication. The tool supports UTF-8 credential encoding and warns about username colon edge cases that can break parsing on some servers. All processing is local and no credentials are sent externally.

Direct Answers

Is Basic Auth just base64 of username and password?

Yes, which is exactly why it must be protected by HTTPS and not treated as encryption.

When is Basic Auth still reasonable?

Mostly in legacy systems, internal tooling, or service integrations where the transport and access boundaries are already tightly controlled.
