Looking to set up Two-factor Authentication (2FA)?

Find out how in our step-by-step article.

An authenticator app is usually installed on a smartphone and generates a 6-8 digit code every 30 seconds. The code can be used for signing in, trading, depositing or withdrawing funds from your account or as a Master Key. Note: 2FA for each of these account actions needs to be setup separately.

How does an authenticator app work?

The codes are generated from a secret key that is shared between the service you are using (like Kraken) and your device, as well as the current time.

The secret key provided at the time of download is all that is needed for backup.

Note: authenticator apps are not tied in any way to your SIM card or phone number and that improves security by protecting your account from SIM swapping.

Where can I get an authenticator app?

There are a variety of authenticator apps that you can download for your smartphone.

A popular example is Google Authenticator, which can be found in Google Play and the iOS App Store.
