A Hardware Security Key is a small physical device used for additional security next to your password and is considered to be one of the most secure ways of two-factor authentication (2FA). Most Hardware Security Keys are very simple and you only need to touch or tap a button while it is plugged into the USB port of your device.
At this moment only sign-in 2FA can be secured with both FIDO2 and Yubico OTP protocols. Sign-in 2FA and the Master Key support Hardware Security Keys that use the FIDO2 protocol. Funding 2FA only supports the Yubico OTP protocol.
Functions | Available Hardware Security Key protocols |
---|---|
Sign-in 2FA | FIDO2 |
Trading 2FA | None |
Funding 2FA | Yubico OTP |
Master Key | FIDO2 |
Each function needs to be set up separately. To learn more about the 2FA functions above, you can review this support article.
