A 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 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. We expect to support FIDO2 for all 2FA functions in the near future.
|Functions||Available Security Key protocols|
|Sign-in 2FA||FIDO2, Yubico OTP|
|Funding 2FA||Yubico OTP|
|Master Key||Yubico OTP|
Each function needs to be set up separately. To learn more about the 2FA functions above, you can review this support article.
