Matt Stauffer has posted the eleventh part in his series looking at new features of the latest release of the Laravel framework (well, version 5.1). In this tutorial he shows you how to setup and configure the login throttling for your Laravel-based application with the help of the Laravel Throttle package.

Whether or not you know it, any login forms are likely to get a lot of automated login attempts. Most login forms don't stop an automated attack trying email after email, password after password, and since those aren't being logged, you might not even know it's happening.

The best solution to something like this is to halt a user from attempting logins after a certain number of failed attempts. This is called login throttling, or rate limiting. Graham Campbell wrote a great package called Laravel Throttle to address this in previous versions of Laravel, but in Laravel 5.1 Login throttling comes right out of the box.

He shows how to use the ThrottleTrait in your AuthController to have some of the "behind the scenes" work done for you. He shows you how to update your view to relay the possible error message back to the user (and includes a quick screencast of the result). He ends the post with a quick look at what the throttling functionality is doing under the covers: creating a temporary cache item based on username+IP address as a "lock" indicator. Finally, he points out two properties you can find on the auth controller to give a bit more detail on the current configuration: lockout time and max login attempts.
