Using the Security Key, companies have seen zero successful phishing attempts.
The Security Key 5Ci is FIDO and FIDO2 certified. It works with Google Chrome or any FIDO-compliant application on Windows, macOS or Linux and with applications that provide FIDO, FIDO2, or one-time-password (OTP) support and through Chrome, Firefox, or Edge browsers.
The Security Key offers superior security by combining hardware-based authentication and public key cryptography to effectively defend against phishing attacks and eliminate account takeovers. It offers multi-protocol support including FIDO2, OTP, OATH HOTP, U2F, PIV, and Open PGP. Users have the broadest options for strong authentication including not only two-factor authentication but also support for single factor passwordless login and multi-factor authentication in conjunction with user touch and PIN.
The Security Key 5 Series helps organizations accelerate to a passwordless future by providing support for the FIDO2 protocol. FIDO2 supports not only today’s two-factor authentication but also paves the way for eliminating weak password authentication, with strong single factor hardware-based authentication.
