When enabling two-factor authentication, Selly displays a large and clear warning message stating that you must save the recovery code.
Without this recovery code, Selly will not be able to recover your account.
If you saved the recovery code as expected, simply create a new account and create a ticket contacting us explaining the situation. Be sure to include the locked account's username, email address and of course, the recovery code. We may ask some further questions to ensure your ownership of the account.
