Create a clean implemented wordpress plugin for user authentication as a POC

We want to create a proof of concept (POC) with a clean implementation. Your task is to create a wordpress plugin, which does following: - on a specific wordpress page, the user can enter a CODE - the CODE is in the POC a set or 10 UUIDs, which is getting fetched from the database - if the CODE was found on the database, the user gets a notify that the code is valid - if the CODE is valid, the user can click on button register - if the CODE is invalid, he gets a notification, that the code is invalid (without the need to click onto the button) - after the registration, the UUID is getting marked as used and also the UUID is getting the update of the Operating System, the IP and the system username known by the user, along with the registration localized/timezoned Datetime - after the registration, the user is automatically logged in into the wordpress site. - Also the users is getting a default role assigned (e.g. a behaviour like [login to view URL]), so the user can see protected pages - wordpress pages can be assigned to be only visible by a validated registration structure of the registration table - ID - UUID - username - given name - surname - e-mail - registrationDate (localized datetime) - lastLoginDate (localized datetime) - systemUserName (from OS) - clientIP - browser
