Maybe I'm misunderstanding, but I thought the whole idea of ubikey was that it proves who I am because I have it, no? If I own 4 ubikey, how does the system know whether I'm really me, or if I'm someone whose stolen one of my ubikey?
- luhn 8y agoIf you have one Yubikey, how does system know if it’s really you or someone who stole your key?
- LeonM 8y agoIt is a second factor, so the'll also need to know your password. You will notice your key missing, then you can disable that key with your backup key. With only a password, it becomes a lot harder to notice someone stole your pw.
- icelancer 8y agoRight. That also applies to N number of keys, too.
- joesb 8y agoThe different is, if you have 1 U2F key, people who steal your U2F key gain access to one half of the two factors for ALL services you use. With 4 U2F keys, people who stole 1 of your U2F keys gain that one factor for only the services that you tied to that keys.
- fulafel 8y agoU2F is much narrower than full Yubikeys.
