On the SitePoint PHP blog there's a new tutorial posted from Christopher Vundi showing you how to create a password-less login system using "magic links". These links allow users to log into a service without requiring a password using a one-time code and a special URL.

Authentication is something that has evolved over the years. We have seen it change from email – password combination to social authentication, and finally password-less authentication. Actually, more like an “email only” authentication. In the case of a password-less login, the app assumes that you will get the login link from your inbox if the email provided is indeed yours.

[...] In this tutorial, we are going to implement such a system in a Laravel app. The complete code can be found here.

The tutorial then walks you through some of the setup of the application environment - creating the Laravel project, building out the database and running the "make:auth" to generate related controllers/views/models. They show you how to change the login link to point to the new "magic link" functionality and the matching controller and view. The tutorial then shows how to generate the tokens, email them to the user with the special URL and validate them once they come back in.
