Create a MERN Project

Have to create a website using mainly React and MongoDB and should also explain the code before submitting so that we can do our own modifications if needed. Website is similar to an online learning platform where courses can be just viewed with the given logins. No need of adding purchase course, signup page etc. There should be strict security such that only one device can be registered. If the user want to login to other device he should get approval from admin. Admin page should be different to add new logins for course access and few other features should be available.
