FIDO  security keys are small USB dongles that enable secure login to websites and applications supporting FIDO2 WebAuthn and classic FIDO (U2F) standards. 

Token2 T2F2 security key combines hardware-based authentication, public-key cryptography, TOTP/HOTP, U2F, and FIDO2 protocols to protect your accounts. This type of security devices provides the highest level of multi-factor authentication of user accounts with Twitter, Facebook, Gmail, GitHub, Dropbox, Dashlane, Salesforce, Duo, Centrify and hundreds more HOTP, U2F, and FIDO2 compatible services. No additional tools or applications are required and the login process is simple and reliable. Just insert the Security Key into a USB-A slot and authenticate with a simple touch. We also sell a compact USB-A to Type-C adapter, so you can use the same key with devices with USB-Type-C slots. The T2F2-Bio security key does not require a battery nor network connectivity so it is always on and accessible.
