You can turn off this feature entirely so visitors see a "403 Forbidden" error instead of a list of files. For Apache: Options -Indexes For Nginx: autoindex off; in your configuration file. 2. Use a Robots.txt File
Use services like Have I Been Pwned or built-in browser password monitors to alert you the moment your email or credentials appear in a public leak. For Organizations and Webmasters:
: Attackers search for strings like intitle:"Index of" password.txt to find plain-text files on public servers that might contain usernames, passwords, or other "verified" credentials for various services. index of password txt verified
