I am trying to create a unique URL that get sent to users via email, once clicked they result in a unique page where the user can his data for the creation of an account. 

The URL should be unique and can port, in a scure way, some data about the account which the user is going to create like a prefixed email address or any other field. 

I don't know the exact name for these kind of URLs but i saw it used by google and i want to implement the idea in my nodeJS based platform, so how can i do that ?.
