Quick PHP Password Protection Readme

Quick PHP Password Protection is a single user PHP login system which is secure, quick to implement, and requires no database. Perfect for small web apps, scripts, and personal pages which only have a single admin using them.

Example Usage

<?php
require_once "../quickprotect.class.php";
$quickprotect = new quickprotect();
$quickprotect->checkLoginAndDirect();
?>

That's all it takes! One line of effective code (not counting the class include and init), and you've password protected a page!

Features

Secure. Tested brute force and SQL Injection proof.
Extremely easy implementation. One line of code, and you're done.
No database required. Settings stored in INI file.
Note: this is a single user system ONLY. Multiple users are not supported. This is designed for small projects, web apps, and personal pages.

How to implement

Step 1: Upload login.php, login.ini.php, and quickprotect.class.php to your server
Step 2: Configure login.ini.php with the appropriate settings
Step 3: Implement the password protection in your app by using the code above. Whichever pages contain those 3 lines of code will be password protected

$quickprotect->is_logged_in(); //Returns true or false

How do I change a password?

Simply pass those values to the function, and your password will change

Method 2: Manually

Change the value of ADMIN_PW in the INI file to the sha1 hash of the password you want to use.
