5.My 2FA needs to change or is not working. What should I do?

Sometimes we need to make changes to our 2-factor authentication. This happens most often when we change a phone number or get a new mobile phone. 

Bitmain's 2FA specialist can clear your information so that you can update it. Simply submit a support ticket and include:

1. A clear picture of an official photo identifications. This is usually a driver's license or passport, but can be any government issued picture ID. 

2. A picture of you holding the identification. 


The security of your Hashnest account is something we take very seriously, for your protection. For that reason we require this confirmation of your identity before we make changes to your account access.
