Practical guidance
Store credentials outside the public web directory. Besides generating a hash, configure the protected section and credentials file path in Apache or Nginx. Verify that unauthenticated access is denied after configuration.
Before using this tool
Define what you need from htpasswd generator and prepare the relevant input. When diagnosing a live service, record the test time and connection conditions so you can compare results after configuration changes. Check findings against the documentation for your software.
