Password Protected Pages

Curious about what strategies are out there for increasing the security of password protected pages. (e.g. a single page that requires a password to be entered in order to view the contents)

I know plugins like Limit Login Attempts protect sites from brute force attacks on the admin side but does anyone know of anything that helps protect sites similarly for password protected pages?

Would love a quick fix. That said, I’m open to moving away from password protecting the page with a single password to requiring people to create an account to access information if that’s the only way to protect the information. In that case, would be interested in recommendations for how to do that.

Thanks for any insights you can offer!
