WhatsApp Web might soon let you log in with just a fingerprint

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. If that’s something you find to be fiddling or irritating, you’ll be pleased to hear that it could be about to change.
