Majority of cryptocurrency exchanges support two-factor authentication through
Google Authenticator (GA). This is a simple and convenient application that does not require creating an account and any settings. It is enough to install
GA and connect it to your account. The data is stored only on the user's device. Google Authenticator is available on iOS, Android and BlackBerry OS.
