This plugin allows you to use a third-party JWT Authentication service in order to allow your users to access the Rest API of your WordPress website/blog, e-commerce, etc. For example, you’re handling the authentication part on a different project but want to use WordPress features via RestAPI and in meantime keeping the content protected.
After installing and activating the plugin, under the settings page, you need to define the API Endpoint where the JWT Token will be validated. Your API Responses should be adapted as suggested on the settings page.
This plugin will not affect the current users that use the dashboard.

While WordPress is slowly but surely becoming a complete application framework and JSON REST API is huge step in this direction, there is a large number of WordPress users that do not need advanced features like those offered by WordPress JSON REST API. This plugin helps them to turn those advanced features off and not worry about it.
While other similar plugins disable JSON REST API functionality only for anonymous users, Kill JSON REST API completely disables the framework for all users and removes links and tags from head element.

Kill JSON REST API

Completely disables JSON REST API for both registered and anonymous users in WordPress 4.7.* and removes API links and tags.
