What is 2FA?

Two-factor authentication (also known as 2FA or 2-Step Verification) is a technology that provides identification of users through the combination of two different components. CoinEx currently supports the following two 2FA tools: Google Authenticator and SMS code. When you are logging into your account, you are supposed to enter password as the first verification and enter 2FA code (SMS code or GA code) as the second verification to set up double protection for your account. For your account security, 2FA verification will be enabled by default after you bind your mobile phone or Google Authenticator.

You can follow the guidelines below to bind GA and mobile number:
