How Do I Password Protect a WordPress Site Without Plugins?

Password protection for a WordPress site can be done without utilizing any plugins. The method involves creating a custom WordPress theme and setting up a custom password protection plugin. This plugin will require the user to enter a password before accessing the site. This password can be stored in a secure location, such as a server-side authentication plugin.

Once the password is stored, a user will only be able to access the site if they know the password. This method provides a level of security for users that does not require the use of plugins or additional services.
