Facebook's WhatsApp has quickly risen to become one of the most popular instant messaging apps available today, among many of the other well-known options out there like Kik and Snapchat. And it's showing no signs of slowing down.

WhatsApp Web

A desktop web version for WhatsApp is available, but it functions a bit differently than other web-based IM services you may be familiar with. WhatsApp Web uses your smartphone to communicate through the WhatsApp service.

To use WhatsApp on your computer via the web, you must first have it installed on your smartphone. After doing so and setting up your WhatsApp account, you visit the WhatsApp web app site and scan the QR code using WhatsApp on your smartphone to make the connection. 

This is not as complicated as it may sound. For the steps for setting up WhatsApp on your desktop or laptop, check out the WhatsApp Web FAQ.
