Protocols

Our website works with Yubikey using the Yubico OTP protocol.

We plan to add FIDO U2F and FIDO2 protocol support in the near future.

Models

2FA devices that currently work with Kraken (support Yubico OTP):

• YubiKey 5 Series
• YubiKey 5 NFC *
• YubiKey FIPS series
• YubiKey 4
• YubiKey 4 Nano
• YubiKey NEO NFC *

2FA devices that currently do NOT work with Kraken (do not support Yubico OTP):

• Security Key by Yubico
• Security Key NFC by Yubico
• Google Titan Security Key

Yubikey NFC on mobile

Since the YubiKey 5/NEO NFC can't be directly plugged into a phone, it uses NFC to communicate with the YubiKey Authenticator app. The app then generates an OTP code which you can copy into your phone’s clipboard.

To paste this code on the Kraken login 2FA page (after entering your username and password), you will need to click the “Enter YubiKey code manually” link.

Custom Configurations

It is not possible to set up a YubiKey for Kraken using the custom configuration option within YubiKey Manager. 

If you tried to add a custom configuration, please delete it and then follow our YubiKey setup instructions. Only afterwards can you swap the configuration between Slot 1 and Slot 2 (if so desired).

Do not try to edit the configuration created by Kraken. It will prevent your YubiKey setup from working with your Kraken account and you will need to delete it and start over again.
