Those who want to spy on your WhatsApp activity have another approach – and one that’s free – with the WhatsApp Web Service. Users can use the messaging app directly from their personal computers, which although convenient, unfortunately, is also subject to some risk. “Can I borrow your phone quickly?” might not be as harmless as it sounds. To get started spying, the snoop just needs the target’s smartphone long enough to take a photo of the QR code displayed on the computer screen using the WhatsApp spy app on the victim’s smartphone. Once that’s done, the snooper can then view the victim’s entire chat history on the PC and comb through it at leisure. The flow of juicy details continues as the chat history gets updated each time the victim’s smartphone connects to the home Wi-Fi network.
How to check if you are being spied on in WhatsApp Web
With WhatsApp Web you can easily see if you’re being spied on and put it to a stop by checking your settings. In the mobile WhatsApp app, go to the Settings and look at the area called WhatsApp Web/Desktop. Here you can see when the service was last active. So, if you’ve never connected WhatsApp to your PC, or you see entries that aren’t from your own activity, don’t waste time and hit the “Log out from all devices” button to disconnect from the sinister connections.
