Two way authentication factor
Two-factor authentication, also known as 2FA or two-step verification, is an extra feature designed to
prevent anyone but you from accessing your account and digital wallets on SellBitcoin™. By requiring two
forms of identity verification: your password and an authentication code. 2FA is the current standard to
make sure accounts are safe from unauthorized access since they would also require access to your mobile
device or email account, depending on how you set it up.
