Basic Auth Credentials Generator
HTTP Basic Authentication requires encoding "username:password" in base64 and sending it in an Authorization header. Getting the header value right — including the 'Basic ' prefix and the correct base64 padding — is fiddly to compute by hand every time you need a test credential. This generator produces a random username, a 16-character password, and the exact Authorization header value you need, all in one output you can copy straight into a curl command, a Postman request, or a test fixture. There are no inputs: each run draws a username from a realistic service account list (admin, testuser, svc_api, demo, devops, ci_runner) and generates a random 16-character password using a character set that avoids visually ambiguous characters. The base64 encoding is computed by the generator itself — the output shows the plain username and password alongside the ready-to-use Authorization: Basic <encoded> header. These credentials are for development and testing only. Never use a generated pair on a real protected service, and always serve Basic Auth over HTTPS: base64 is encoding, not encryption, and the credentials are fully readable to anyone who intercepts the request.
How to use

Detailed instructions
- Click Generate to produce a username, password, and header.
- Copy the Authorization header into your request or test.
- Or use the username and password directly in a client.
- Generate again for a fresh pair whenever you need one.
Use Cases
- •Testing endpoints protected by HTTP Basic Auth
- •Generating the Authorization header for a request
- •Placeholder credentials in config and documentation
- •Learning how Basic Auth encoding works
- •Seeding a development environment with test logins
Tips
- →Only ever send Basic Auth over HTTPS — base64 is not encryption.
- →Use these for testing; never reuse them on a real service.
- →The header format is "Authorization: Basic <base64 of user:pass>".
- →For production, prefer token-based auth over Basic Auth where you can.
FAQ
what is http basic auth
HTTP Basic Authentication is a simple scheme where the client sends 'username:password' encoded in base64 in the Authorization header. It is easy to implement and still common for internal tools and APIs, though it must always be used over HTTPS since base64 is encoding, not encryption.
is base64 secure
No — base64 is encoding, not encryption, and anyone can decode it instantly. That is why Basic Auth must only be used over HTTPS, which encrypts the whole request in transit. The base64 step just packages the credentials; it provides no secrecy on its own.
are these credentials safe to use
They are random and intended for testing and development only. Never reuse a generated username and password on a real protected service, and always serve Basic Auth over HTTPS so the credentials are not exposed in transit.
does the generator produce the full Authorization header value
Yes. The output includes the complete header line — 'Authorization: Basic <base64-encoded-value>' — ready to paste into a curl -H flag, a Postman header field, or a test. The base64 encoding is computed by the generator from the 'username:password' string, so you do not need to encode it yourself.
