Does anyone know of a plugin that will allow for a simple access/invite code to be given out, and when entered, will allow access to a certain page?
I'm looking to only have one input field and no user registration needed to access a certain page of the site, and to just be able to give out unique codes that will grant access.
I can't find anything like this that isn't a full user membership plugin. Any help or point in the right direction is much appreciated.
