Basic Auth Generator
Generate HTTP Basic Authentication headers from username and password instantly
What is HTTP Basic Authentication?
HTTP Basic Authentication is a simple authentication scheme built into the HTTP protocol. The client sends a Base64-encoded string of "username:password" in the Authorization header with each request.
Is Basic Auth secure?
Basic Auth alone is not secure because credentials are only Base64-encoded, not encrypted. Always use it over HTTPS to prevent credential interception. For production apps, consider more secure alternatives like OAuth or JWT.
How do I use Basic Auth with curl?
Use the -u flag: curl -u username:password https://api.example.com, or use the -H flag with the generated header: curl -H "Authorization: Basic dXNlcjpwYXNz" https://api.example.com
Can I use special characters in username or password?
Yes, this tool handles Unicode characters properly. The credentials are UTF-8 encoded before Base64 conversion, following RFC 7617.
