Age Okay is a highly customisable age verification plugin for WordPress.
On the pages you choose, it will cover the content of your website with a customisable age verification form. This form will continue to show to a user until they have verified their age, at which point their verification will be saved in a cookie for the length of time set by the admin. This length of time can be from only as long as the browser is open, to multiple years.
There are 3 important pages which can be found in the WordPress admin navigation under ‘Age Okay’: 
1. Editor – This page allows an admin to customise every aspect of the look of the age verification form. 
2. Settings – This page allows an admin to set which pages the age verification form should we shown on. 
3. Translations – This page is unlocked in the pro version; it allows an admin to provide multilingual versions of the text content of the form.
The goal of this plugin is ease of use, and has been built so that a website owner will not need any coding experience to customise the plugin to do exactly what they need. However, in the PRO version there is some functionality that can be added using additional coding, more information can be found in the Age Okay documentation.
Please be aware, this plugin will not stop a user from viewing the content of your website if they so wish, and so should not be used as a substitute for proper securing of any sensitive content.
