I have lost (broken, hard-reset) my phone out of the blue and I can not generate any new codes. How do I reset the 2FA?

Contact MinerGate Support team. You will be asked to provide some additional information about yourself and/or your account as the team needs it to verify you as the real owner of the account. This information can include some recent transactions (hashes, dates, amounts), actual balances, IP-addresses that you have recently logged in from. The more facts you provide, the better. If you provide it in your original request, this will strongly expedite the process.

After all the info is on the table, MinerGate Support will validate it and disable the 2FA for your account manually.
