Deevop supports Two-Factor Authentication via YubiKey™.

To activate the Two-Factor Authentication:
Choose User Menu Edit my profile

Select Two-Factor Authentication.
YubiKey is the only Authentication Method available.
YubiKey

- Click on the Secure Code field and press the Golden botton of the YubiKey.
If the YubiKey validates successfully you will get a list of emergency passwords.
We recommend printing these passwords out and keeping the printout in a safe and accesible location, eg your wallet or a safety deposit box
After successfully setting Two-Factor Authentication to your user, when you enter your login and password details in the login field, a new third field will appear named "Secret Key". To fill this field click on it and press the golden button of your key.
Once you logout, you will need your YubiKey to access your deevop account.
In order to remove the Two-Factor Authentication, press the button "Remove Two-Factor Authentication"
