Passwords suck, Multi Factor Authentication is hip, everyone wants to use it, but most methods rely on some kind of generated One-Time passcode, which are as vulnerable to phishing as the passwords they should help protect. Other possible factors, like app-based authentication also bring similar design flaws to the tableA good alternative to insecu…
