Open Source PHP Login System

I’ve been using this PHP login system for a while now, it’s called Quadodo and it’s completely free and open source under the GPL license. One of the many benefits I find with it is that it’s 100% customisable while still being secure.

It has many features, like the forgotten password page and the registration page. If you’re running a very small site but would like a login system for certain content, I would strongly recommend Quadodo.
