In this video we look at the Protected Pages module for Drupal 7. This module allows for password protection on paths in Drupal. In other words, this module will prompt a visitor to a specific page to enter a password before they are able to see the content.
This is one of those modules that exists to just make this use case simple. There are a ton of other ways to accomplish this with permissions and roles in Drupal, but it is always nice to have a simple way to accomplish this task.
