# Overview

[![Build Status](https://travis-ci.org/duosecurity/duo_php.svg?branch=master)](https://travis-ci.org/duosecurity/duo_php)

**duo_php** - Duo two-factor authentication for PHP web applications: https://duo.com/docs/duoweb

This package allows a web developer to quickly add Duo's interactive, self-service, two-factor authentication to any web login form - without setting up secondary user accounts, directory synchronization, servers, or hardware.

Files located in the `js` directory should be hosted by your webserver for inclusion in web pages.
