If you have no longer access to your 2 fa device, please enter your secure code which you was shown during setup of this 2nd factor authentication into a 2 fa generator (Apps like Google Authenticator, Authy etc.).
If you failed to write down the secure code, please provide us the following information to verify yourself as account owner:
1) Your account user name
2) When did you join CoinTracking?
3) Which exchanges do you frequent?
4) Name 3 coins we could find on your dashboard and their amounts
We will then remove your 2 fa manually.
Please send us your answers in a support ticket (https://cointracking.freshdesk.com/de/support/solutions) or via E-Mail to email@example.com.
