Can those things break? What if it does? Is all your data lost?
- Insanity 6y agoBreak as in: smash it to pieces with a hammer? Surely so :p
- malandrew 6y agoI would assume that you can have more than one so you have a backup, but if not, yeah that seems like a serious single point of failure.
- fbnlsr 6y agoI've had a Yubikey on my main keychain for about 5 years. I dropped it dozens of time and it never broke.
- kabdib 6y agoSame here; the YKs on my keychain take an incredible amount of abuse, rubbing against keys and other objects all day long, for years, and I've never had any trouble. Contacts don't show appreciable wear (and they've had thousands of insertions). One thing I'd really, really like is for a way to distinguish multiple YKs. The things are so durable that they won't take a permanent marker, and I've had to gouge identifiers on them, clip off corners and so forth.
- jolmg 6y agoIn the case of Yubikey's OpenPGP smartcard emulation, you can generate the key on a computer, write it to the Yubikey, then do whatever kinds of backups of the keys you like. If the Yubikey is destroyed or lost, you can buy a new one and write the key to it from a backup. If I recall correctly, writing the key is an OpenPGP smartcard feature, so it should work on any hardware key that supports acting as an OpenPGP smartcard.
- foxtrottbravo 6y agoThe Yubikey documentation recommends always buying them at least in pairs. And configure them both for access. If you use either a Static Password an HMAC-SHA1 Challenge-Response or TOTP with the key you can easily backup the secret material used to program the key and replace the key if one fails. Store backups safely.
