Why SMS 2FA is insecure & why you shouldn’t give out your mobile number

  1. Why you shouldn’t give out your mobile number freely, to anybody.
  2. How SIM swaps actually happen.
  3. What is a better way of securing yourself online

Are you scared? You should be!

All it takes is a little social engineering and the “security” is totally void.

So what can be done about this?

Two things come to mind:

  1. Don’t use your cellphone for 2FA. It’s not secure and can’t be trusted. If you must, for, say, a single exchange, don’t re-use your mobile number. Get a burner mobile. Alternatively, just use a better exchange.
  2. Use Digi-ID by DigiByte. It’s far safer and removes many of the incentives to ever even attempt SIM-jacking.
  • We know SMS-2FA is insecure
  • We know we shouldn’t use it
  • We know there are far better, safer, faster, and more secure alternatives
