WhatsApp has a plan to tighten account security – here's what you should know – TechRadar

While WhatsApp is most commonly used on mobile devices, there are also desktop apps available, as well as a web app. However, because the messaging service is (for now, at least) tied to your phone number, you still need to have your handset nearby for authentication before you can log in on a PC or laptop.

The current method of authentication involves using your phone’s camera to scan an on-screen QR code to gain access to your account. That can be fiddly or irritating, and leaves your account vulnerable if your phone is stolen, but it could be about to change.
