Login By QRCode

You can login or signup in normal way in both desktop and android
You can also link your authorized android account to the desktop by scanning a QRCode!

Bot

Connect your account to a bot. (Only for developers)
A bot is only an HTTP api link, You can develop the api in all programming languages.

This one is a "Hello World!" bot code written in PHP.

<?php
