How to Build Your Own Virtual Phone in Minutes

You only need the phone number as an identifier to register for Signal, not to login . Same for WhatsApp. I no longer have the original phone # I signed up with for these services, but have been logging in just fine for months. They never used SMS 2FA (perhaps because it’s a terrible security practice, and Signal developers certainly know better).

You no longer your sim-card, right? What will you do if you buy a new smartphone? I want to see how you’ll be able to login to your Whatsapp account on your new smartphone if “phone number is only to register once, not to actually login”.
