What is a Yubikey?

A Yubikey is a hardware authentication device that can be used for Two-factor Authentication (2FA) on your Kraken account. Yubikeys are used for Two-factor Authentication (2FA) by inserting the device into the USB port of your computer and then tapping or touching the button on the device to produce a one-time passcode.

What does a Yubikey do?

A Yubikey emits one-time passcodes when tapped or touched. A Yubikey can be used to enable Two-Factor Authentication (2FA) for login, deposits & withdrawals, and as a Master Key on a Kraken account. 

Where can I get a Yubikey?

You can purchase a Yubikey on Yubico's website, the producer of Yubikeys. Please make sure the Yubikey you buy meets our compatibility requirements.

Why should I use a Yubikey instead of other 2FA options?

There are a few reasons why a Yubikey may be preferable over other 2FA options:

Security: Having a physical device that is only used for Two-factor Authentication (2FA) may result in users guarding it more closely. As such, accounts of Yubikey users may be less likely to be compromised. Also, considering that a Yubikey is not a very commonly used security mechanism, an attacker may not realise that it is of any value.

Simplicity: All you need to do on a Yubikey is simply plug it into your computer’s USB port and touch or tap a button. No need to rely on an app, worry about your device's battery running out, or software crashing.

Human Error: We see a lot of lost phone tickets at the Kraken support desk. In our experience, a client is less likely to lose a device specifically used for Two-factor Authentication, than a device like your phone, that you carry around all the time.
