Show HN: A phone-based login system in just a few lines of JS

[drazvan]

To show off the power of our VeriFi system (https://www.veri.fi/) I've spent some 10 minutes today and created a very simple login system for websites that only requires the user to enter his/her phone number. No usernames, no passwords. It's live at https://www.veri.fi/phonelogin.html , feel free to give it a try.

Your phone number is not sent to the site you're logging on to, it is only sent to our server and replaced with a unique token that the server can use as your user id. When the server requests it, VeriFi places a voice call to your phone number and asks for your permission to log in. If you say "yes", you are logged in.

Comments are welcome! Razvan
