A simple plugin that allows you to restrict access to certain pages on your website to only logged in users quickly and easily. This plugin can be useful to those who do not need overly complicated membership systems, and to those who want to password protect a group of pages but don’t want to password protect each page individually, forcing the users to log into each one.
It is simple to use. First select whether you want to password protect all pages by default, and want to choose which pages are public. Or choose to allow all pages to be public by default, and choose which pages are password protected.
When non-logged in users try to access a password protected page they will be redirected to the WordPress login screen. Once logged in, they will be redirected back to the requested page and will not be asked to log in again on subsequent pages.

‘Nucuta Password Protect’ is a security plugin which password protects wordpress websites. Requires PHP 5.6.30 or Above.
The plugin uses a custom password, and therefore it’s completely independant from default wordpress password uses to access to the admin area of the site. Users can be restricted to access the site either based on their user group or altogether.
The available user groups are “editor”, “author”, “contributor”, “subscriber”. if a particular group is excluded from protecting from the custom password, users belong to that group won’t be asked the password. Clicking on the log off button logs off from the entire website, meaning the user has to enter the password to access the site again. By default, all users (both guests and registered logged in users) are required to enter the password before accessing the site, but by configuring, logged in users can be excluded. The plugins blocks not only visitors, but also bots, spiders, and all kind of crawlers.
Custom message can be set for both logged in/non-logged in users, A separate login page is provided to login purpose. Password is salted before storing in the database, and therefore security is top notch.
