Frequently Asked Questions

What is Basic Authentication?

Basic Authentication is a simple authentication scheme built into the HTTP protocol. It requires a username and password to be sent in the HTTP header with each request. The username and password are combined with a colon, encoded in Base64, and prefixed with "Basic " to form the value for the Authorization header.

Is Basic Authentication secure?

Basic Authentication by itself is not secure as the credentials are only Base64 encoded, not encrypted. This means they can be easily decoded if intercepted. It should only be used over HTTPS connections to ensure the data is encrypted during transmission. For highly secure applications, consider using more robust authentication methods like OAuth or JWT.

How do I use this Authorization header?

The generated Authorization header should be included in HTTP requests that require Basic Authentication. You can add it to your requests using various methods:

  • In API clients like Postman or Insomnia, add it under the "Headers" tab
  • In curl, use the -H option: curl -H "Authorization: Basic abc123=" https://example.com/api
  • In JavaScript fetch API: fetch(url, { headers: { Authorization: 'Basic abc123=' } });
  • In Axios: axios.get(url, { headers: { Authorization: 'Basic abc123=' } });
Is my data secure when using this tool?

Yes, all processing occurs locally in your browser. Your username and password are never sent to any server, and no data is stored or logged. The entire encoding process happens on your device, ensuring your credentials remain private and secure.
