Then you have the .htpasswd file alongside that or in a subdirectory, which contains the username and hashed password.
If that doesn't help, make an issue on my repo and we can work it out there. Today I added password protected pages as a built-in feature, but it would need much longer in the oven before I could suggest switching an existing site over.
