A YubiKey is a small USB or NFC key that proves identity to a website over FIDO2 or WebAuthn, which is the one second factor that resists a real-time phishing proxy. One key covers many services, needs no battery or driver, and can hold a PIN for passwordless sign-in. Organizations hand them to administrators and finance staff first, then to anyone with access to email.
