About Basic Auth Generator

The Basic Auth Generator by TooliFyra is a free online tool that creates HTTP Basic Authentication headers from your username and password credentials. Basic Authentication is one of the simplest and most widely used methods for protecting HTTP resources. The tool generates the Base64-encoded credentials and provides the complete Authorization header, ready to use in API clients, cURL commands, and development tools.

How to Use

  1. Enter your username in the first input field provided.
  2. Enter your password in the second input field.
  3. Click "Generate Auth Header" to create the Base64-encoded authorization value.
  4. Copy the output in your preferred format: raw value, full header, cURL, or Fetch API.

Frequently Asked Questions

Basic Authentication transmits credentials as Base64-encoded text, which is easily decoded. For production use, always use HTTPS to encrypt the connection. Basic Auth over HTTPS provides adequate security for many use cases.
No, all encoding happens entirely in your browser using the btoa() function. Your username and password are never transmitted to any server or stored anywhere.
Base64 is a binary-to-text encoding scheme that represents binary data as ASCII text. In Basic Auth, it encodes the "username:password" string for safe transmission in HTTP headers.
Click "Copy cURL" to get the complete cURL command with the Authorization header included. Paste it directly into your terminal for testing protected API endpoints.
