Google Authenticator is a security application developed by Google that generates 2FA (Two-Factor Authentication) codes to enhance the security of online accounts. When 2FA is enabled, in addition to the regular login password, users must enter a randomly generated 6-digit authentication code from the Google Authenticator app.
This application helps prevent account takeover attacks—even if a hacker obtains your password, they cannot log in without the 2FA code.

For trading accounts on centralized exchanges (CEX), security measures are implemented at multiple levels, including:
