Plugin recommendation request: password protecting specific pages
I have a public Wordpress website. I am now looking however to password protect some specific pages (i.e. restrict access to these pages to just visitors who have a valid password). The website currently doesn't have any data entry elements for website visitors.
Thus far all plugins that I've found that offer this functionality are premium ones with hefty monthly subscription prices.
So my question: does a free plugin that offers what I'm looking for also exist?
