It’s a hardware authentication key. Kinda like a USB flash drive.
You know how some services offer multifactor authentication (MFA), also referred to as two factor authentication (2FA)?
There are typically two types offered: time-based one-time passwords (TOTPs) where you have 30-60 seconds to type in a 6-digit code, and SMS-based where they text you a 4-6 digit code (that also expires within a set time frame).
With a Yubikey, you gotta plug in the Yubikey into your computer or phone. Or, there are some models that use near field communication (NFC) and you just need to bring it near the device you’re tryna authenticate.
So rather than typing in those codes you get either from SMS or your authenticator app, you use the Yubikey as your authentication method.
