> Why do you have to use so many? Well, I started out with a Symantec VIP Yubikey many, many years ago. Then, MtGox sent me one for 2FA after some compromise there. Later, I bought a "full-featured" Yubikey for use with GPG and SSH on my desktop / workstation. After that, I got two Nanos so that I could leave one, permanently, in each of a pair of laptops. Shortly after that, I decided I should have a spare -- you know, just in case. At some point, I received another pair of Nanos as free replacements due to one of the issues that Yubico had (weak RNG or something, I think?). Those two and the "spare" are the ones that are still unopened in the package. Finally, (I'm not really sure why but) I bought a pair of the "GitHub" U2F-only Yubikeys when there was some special deal going on. Now that I think about it, I don't think I've ever even used them either. The only ones that I really use are the ones that I leave in my workstation and my primary laptop (primarily used for SSH but, to a lesser extent, for signing git commits and unlocking KeePassXC databases as well). > Why not instead e.g. a LUKS encrypted usb flashdrive? Oh, I've got probably a dozen or so of those also!
