Our previous section covered the basics of the WP REST API and the HTTP authentication that were on the server, which let us install the plugin available on GitHub, courtesy of the development team behind WP REST API. So far, we have only overviewed a method of authentication that will let us use it in a testing environment, but the time has come for us to look into more serious, advanced means of authentication that will be secure enough for us to use on an actual server, and will not compromise the credentials exposed to the requests.
In this part of our tutorial, we will go through the process of setting up the OAuth authentication method that will be used with the WP REST API plugin. We will install the OAuth server plugin and then generate an access token that will help us with the pairing of a conventional application, all this combined with a theoretical overview of the method itself and how it functions.
