To enable two-factor authentication, log into your web wallet and go to → “Settings”. → Switch 2FA ''on'' → Enter your password → Scan the QR code with your mobile device using Google Authenticator or Authy. As a last step you will need to enter the 2FA token to verify if everything is working correctly.
Once your 2FA has been enabled, be reminded that your token changes every minute and can only be generated by the device you have used to scan the QR code.
There can be several reason for which you want to disable 2FA, this is mostly the case when the mobile device on which the token is generated
has been lost. If this is the case, only our support team can help you further. Open a ticket for our support team and we will explain the steps to follow in our reply.
If you still have access to your mobile device and simply want to deactivate 2FA, follow the steps below:
Log in to your web wallet (wallet.btc.com) and go to → “Settings”. → Switch 2FA ''off'' → Enter the 2FA token for verification and click ‘’Disable 2FA’’.
