From today it's possible to enable 2FA (Two Factor Authentication) on your cloud subscription. By using 2FA you can add an extra layer of authentication on top. To enable it just sign-in on https://cloud.kerberos.io, go to your profile page, en press the On button. A QR-code will become visible, which you can scan in with your mobile phone; you should install Google Authenticator.
When you've scanned in the QR-code successfully, you'll see a new entry in your Google Authenticator app. A token will be generated which is valid for a couple of seconds, this token should be entered when trying to sign-in into the cloud application.
