If you no longer have access to the 2FA device linked to your BitMEX account, you can reset your 2FA at https://www.bitmex.com/reset2fa with the reset code you saved earlier. If you do not have it, we can help disable 2FA on your account. Please contact support to have 2FA removed from your account. 

Note:  Before we can disable 2FA on your account, we require you complete identity verification to confirm that the request has originated from the account owner. You can learn more about the ID verification process here: https://bitmex.freshdesk.com/en/support/solutions/articles/13000055145-id-verification-help-sheet
