Passwordless authentication: one step further

“The basic idea is that instead of using a password to authenticate each user, a temporary secret code is sent to them over a secure channel. Email or SMS is that (mostly) secure channel. It’s almost as if the backend server makes up a temporary, one-use password each time a user wants to log in and whispers it in their ear.” — “Passwords are Obsolete” , @Justin Balthrop
