Still using a laptop? Isn’t there a WhatsApp download for a desktop app?
Edit - although you would still need some sort of smartish phone to set that up I am sure.
Haven’t checked the same might be true for the Authenticator app. If you are just dealing with one time number codes there are Firefox plug ins you can use.
Isn’t there a WhatsApp download for a desktop app?
all I know about it is the following:
While the messaging platform already offers cross-platform support, users were able to add a new contact only via the primary Android phone or iOS handset—by adding a phone number or scanning a QR code. ... In a press release, WhatsApp notes that users will soon be able to add and manage contacts through WhatsApp Web and also through Windows platforms or their preferred device, like Android tablets.
