help YubiKey FAQ
Which YubiKey model should I buy for personal use?
Yubico's most popular model for personal use is the YubiKey 5 Series, which includes the YubiKey 5 NFC (USB-A with NFC) and YubiKey 5C NFC (USB-C with NFC). The 5 Series supports FIDO2, WebAuthn, U2F, OTP, and smart card (PIV) protocols. Choose USB-A or USB-C based on your computer's ports, and the NFC variant if you need to tap-to-authenticate with a mobile phone.
What services and accounts support YubiKey authentication?
The YubiKey works with hundreds of services that support FIDO2 or WebAuthn, including Google, Microsoft, GitHub, Dropbox, Amazon Web Services, and many password managers like Bitwarden and 1Password. Social platforms like Facebook, Twitter/X, and Instagram also support hardware key authentication. Yubico maintains a directory of compatible services on their website.
What happens if I lose my YubiKey?
If you lose your YubiKey, you should have backup authentication methods configured on your accounts, such as a second YubiKey (Yubico recommends registering two keys), backup codes, or an alternative second factor like an authenticator app. Most services that support YubiKey allow you to register multiple hardware keys precisely for this reason. Without a backup, account recovery can be difficult since hardware keys cannot be remotely reset or duplicated.
Does the YubiKey require batteries or charging?
No, the YubiKey does not require batteries or charging. USB models draw power from the port when plugged in, NFC models are powered by the NFC reader field when tapped against a compatible device, and the key has no internal battery. This is one of the advantages of hardware security keys over authenticator apps on a phone that requires charging.
