Header Generator
Build an RFC 7617 Authorization header from a username and password, then copy either the full header or just the Base64 credential segment for the client you are working with.
Basic Auth note
Basic Auth is only an encoded credential string, not encryption. Use it over HTTPS and avoid reusing production credentials in shared environments.
Enter the account name or API username you want to pair with the password.
Use the exact password or token string that belongs with the username above.
Encoded credentials
This is the Base64 value for username:password.
Authorization header
Copy this full value into the Authorization header.
How to Use This Basic Auth Generator
Use it as a quick request helper: enter credentials, copy the full Authorization header, and drop it straight into the client or script you are testing.
Enter the username and password
Paste the credentials you need for a quick API request, a curl command, or a temporary testing workflow.
Check the generated Authorization value
The tool creates the RFC 7617 Basic header immediately so you can see the exact value you are about to send.
Copy the full header
Use the complete Authorization header directly in Postman, fetch, curl, scripts, or local debugging work.
Use it only over HTTPS
Basic Auth is just Base64-encoded text, so it should be paired with HTTPS and handled carefully in real environments.
When This Tool Is Most Useful
Basic Auth shows up most often in quick API checks, internal services, old integrations, and protected endpoints where you need a clean Authorization header immediately.
Quick API testing
Generate a Basic header for curl, Postman, or local scripts without manually combining the username and password.
Request debugging
Confirm that the header format is correct when a protected endpoint is rejecting a request.
Legacy and internal services
Use it for environments that still rely on Basic Auth for internal tools, dashboards, registries, or older APIs.
Local-only credential handling
Create the header in your browser without sending credentials to another service while you are testing or validating requests.
FAQs
Does this encrypt my username and password?
No. Basic Auth uses Base64 encoding, not encryption. The credentials are still readable if the transport is not protected with HTTPS.Can I use this for API testing?
Yes. It is useful when you need a valid Authorization header quickly for Postman, curl, fetch, or a local client.Does this run locally?
Yes. The header value is generated in your browser so you can inspect it without sending credentials to another service.What format does the output follow?
It follows RFC 7617 and returns a full Authorization value in the form `Basic <base64(username:password)>`.
