Google Authenticator is Binance's recommended security method, effectively protecting your account from theft. sign up for Binance and bind it ASAP. download the Binance APP to set it up in security settings.
How It Works
Google Authenticator uses a time-based algorithm (TOTP). During binding, Binance gives you a secret key. The authenticator uses this key plus the current time to generate a new 6-digit code every 30 seconds. Since codes exist only on your phone and aren't transmitted over networks, it's more secure than SMS.
