Yubico - Security Key C NFC - Two-Factor Authentication Security Key, Connect via USB-C or NFC, FIDO U2F/FIDO2 Certified - Black

Meet the YubiKey by Yubico: the ultimate hardware security key for phishing-resistant multi-factor authentication (MFA). The YubiKey requires a physical touch to authenticate, eliminating the risk of remote attacks. The YubiKey functions by combining something you know (your password) with something you have (the physical YubiKey) to add an extra layer of security. The YubiKey can also store Passkeys, which replace passwords entirely.

Most cyber attacks begin with compromised account credentials, usually stolen usernames and passwords. Using a security key as two-factor authentication offers a straightforward and effective approach to safeguarding your identity, accounts and devices. Embraced by leading global brands and millions of users worldwide, the YubiKey remains a trusted choice for enhanced security.
