I read your article: did you read mine?

All systems are insecure, but having to have access to two different pieces of hardware in order to get into an account instead of just one does make the system more secure.

As I explained, with 1FA, if I lose my phone and someone unlocks it, or if someone gets access to my laptop, they can get into my account. With a real 2FA, they need access to both pieces of gear.
