You can physically log out of the web version of WhatsApp.

This can be done by clicking on the menu option in the WhatsApp web version and logging out. The first method is to ensure you log out of WhatsApp on the web browser when you are done using it.

In the meantime, there are ways to protect your messages if you are intent on using the web browser version of WhatsApp. The WhatsApp support team acknowledged the potential snooping issue but didn’t commit to a date to possibly solve the problem. Segev further wrote that he contacted WhatsApp support to notify the company of the problem. Should WhatsApp implement a simple notification on the phone whenever the desktop is connected, that is enough to alert someone that they are being watched,” said Segev. “I am surprised that WhatsApp didn’t think this could be an issue. This is a menu option that users have to actively find rather than being passively told via the likes of, for example, a push notification. But this functionality is hidden as users have to press on the 'WhatsApp Web' settings in the mobile app to find this information. Users of WhatsApp are also not overtly notified on their smartphones when the linked application on the web browser is open and being used.įin24 found that WhatsApp technically does notify users on their phones of their last activity on the web browser version. The Fin24 technology team, in turn, found that WhatsApp on the web browser does indeed stay logged in, even after exiting the browser. Segev goes on to write that this issue is "hardly a ‘hack’ or a ‘security breach’" but is just "common sense".įin24 has accessed the WhatsApp web browser functionality and trialled it to determine the extent of this problem highlighted by Segev. “As the phone doesn’t even need to be in the same Wi-Fi zone and just needs an internet connection, the victim can be anywhere in the world for the desktop. “There is absolutely no obvious indication on the phone that the desktop is currently being used and so the WhatsApp user has no idea that someone is spying on the conversations. “Once a computer and a phone have been linked up, anyone with access to the desktop could simply fire up the website and without being prompted for any authentication details, all the information from the phone’s WhatsApp is displayed on the screen,” Segev wrote in his blog post. But staying logged in to WhatsApp on the browser could put you at risk of having your privacy compromised if your computer is accessed by a stranger.
