Customers are saying

Security Key Series vs. YubiKey 5 Series
The Security Key series supports only FIDO protocols (FIDO2, U2F) and is not compatible with the Yubico Authenticator app. Some services require a YubiKey 5 Series for full compatibility. For broader protocol support, including OATH, PIV credentials, and computer logins, consider upgrading to the YubiKey 5 Series.
Works best with a spare YubiKey
A spare YubiKey ensures easy access to your accounts even if your primary YubiKey is lost, providing security and convenience when you need it most. Your spare key can be a different form factor than your primary key, and it will still function the same, as long as both keys are from the same YubiKey series.
Convenient and portable
The Security Key C NFC fits easily on your keychain, making it convenient to carry and use wherever you go, ensuring secure access to your accounts at all times. Simply plug in via USB-C or tap on your NFC-enabled device to authenticate.
Versatile compatibility
Supported by Google and Microsoft accounts, password managers and hundreds of other popular services. It works with Windows, macOS, ChromeOS and Linux. Search for "Works With YubiKey" for list of compatible services.
FIDO-only protocols
Security Key Series is the more affordable security key supporting only FIDO2/WebAuthn (hardware bound passkey) and FIDO U2F authentication protocols. For improved compatibility upgrade to YubiKey 5 Series.
Durable and reliable
High quality design and resistant to tampering, water, and crushing. No batteries or network connectivity required, offering dependable authentication without any downtime. Securely manufactured in USA & Sweden.
