Basic Auth Credentials Generator

Used by developers, writers, and creators worldwide.

A Basic Auth credentials generator produces a username and password pair along with the matching HTTP Basic Authentication header. HTTP Basic Auth encodes "username:password" in base64 and sends it in the Authorization header — a simple scheme still widely used for internal tools, APIs, and testing. This generator hands you a random username, a strong password, and the exact base64-encoded header to use, so you can test an endpoint protected by Basic Auth, populate a config, or learn how the scheme works without computing the encoding by hand. The credentials are for testing and development; never reuse a generated pair on a real protected service.

Detailed instructions

  1. Click Generate to produce a username, password, and header.
  2. Copy the Authorization header into your request or test.
  3. Or use the username and password directly in a client.
  4. 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.
