Lately when I forced to login to FaceBook they will sent a WhatsApp message to my phone number, even though I don’t use WhatsApp. I’d like to see if there is really an account with my number. I tried going to the web client but it seems to be requiring to pair with a device app.
Doesn’t Facebook require your name? WhatsApp would have your phone number already from when friends, family, etc. share their contacts. Maybe they would send a link to install WhatsApp.
