Giving Access by Entering a Name (Events+)

Looking for a way for guests to be able to enter their name and that will give them access to a website. Essentially, this is for wedding websites, so would want to upload a CSV or something with a list of names. NOT email addresses etc. Is this possible with events +?

I hope this makes sense. Basically, guest goes to URL of site, instead of password it says "enter name" this acts as their personal password I guess.
