Secure Without a Password

A few day’s (or maybe weeks) I saw the following project coming by in my twitter feed:

In short, my understanding is that this is a login system that removed the need for a password. It completely relies on your email. So, you want to login, you provide your email address, you receive an email, click the link, done! Just like resetting your password but every time.

I liked the idea. And till today I can’t think of a serious issue that this project would cause. I would like to port it to PHP one day, but I’m pretty swamped at the moment (just like everybody). But I can’t not share this because I really like the concept.

Cheers, Ruben.
