Yubico launches its dual USB-C and Lightning two-factor security key
> Security keys offer almost unbeatable security and can protect against a variety of threats, including nation-state attackers.<p>Alright, I'm not a security expert, but I'm not completely illiterate to basic computer security. Anyone care to chime in how this is much more secure than a two-factor app?<p>Sure there's the obvious, nobody can just copy the two-factor app off my phone with all the codes and have the same codes (I've upgraded phones and taken my codes with me before...) but whose to stop someone from cloning a Yubico key?<p>Again I'm not an expert, but I do want to know if this is purely marketing hype or if there's some security to Yubikey and friends that I'm not aware of.<p>Also pardon me if I confused two-factor as the Google Authenticator app. Too many "factor" terms get a bit confusing after a while.
