Why do I need a YubiKey?
The YubiKey is a device that makes two-factor authentication as simple as possible. Instead of a code being texted to you, or generated by an app on your phone, you press a button on your YubiKey.

How can I log in with one YubiKey?
Just unplug your YubiKey from the old one, plug it into the new one, and you can log in to all of your apps, same as before. You can also use one key to log in to your account on multiple computers. I’ve found the process to be much easier than migrating other 2FA. Really hard to hack.
Can a YubiKey Nano be used on multiple devices?
YubiKey Nano, the smaller device in the picture, is especially designed for scenarios where you keep your key plugged into the computer. You can use multiple keys too. One large YubiKey on your key chain and one Nano for each device you use regularly.
Is the YubiKey U2F a public or private key?
The YubiKey U2F is only a U2F device, i.e. a device that is able to generate a origin specific public/private key pair and returns a key handle and a public key to the caller. Like other inexpensive U2F devices, the private keys are not stored, instead they are symmetrically encrypted (with an internal key) and returned as the key handle.
