Authorization
WWebserver understand the HTTP Basic Authorization.
A directory and all sub directories can be protected with Apache AuthUserFile directive in .htaccess file.
For example:
To protect the directory C:\WWebserver with PHP 7.2.0 create the following .htaccess file in the same directory.
AuthUserFile "C:\WWebserver with PHP 7.2.0\.htpasswd"
AuthName "WWebserver Password protected"
AuthType Basic
require valid-user
After that create a hashed password with standard DES or with PHP SHA512 algorithm.
For example:
php.exe -B "echo crypt('mypassword', rand (10,99));exit;"
The command create the DES hash (DES need the first 2 characters for a salt) 33F7GhkIaweNg of mypasssword
Insert the <username>:<hash> into the .htpasswd file.
myusername:33F7GhkIaweNg
You also can protect a directory with /wwadmin Panel, menu "Directory protection"
