Millions of PC and Mac users will now have the ability to use WhatsApp on their web browser.
The web client is simply an extension of your phone: the web browser mirrors conversations and messages from your mobile device - this means all of your messages still live on your phone.
To connect your web browser to your WhatsApp client, simply open WhatsApp in your Google Chrome browser. You will see a QR code -- scan the code inside of Whatsapp and you’re ready to go.
You have now paired WhatsApp on your phone with the WhatsApp web client. Your phone needs to stay connected to the internet for the web client to work, and please make sure to install the latest version of WhatsApp on your phone.
This is great news for Android,Windows phone and BlackBerry users but unfortunately for now, it will not be able to provide web client to the iOS users due to Apple platform limitations.
