Two-Factor Authentication (2FA) enhances security by requiring two forms of identification before granting access to an account. In cryptocurrency, this typically combines something you know (like a password) with something you have (such as a smartphone).When you enable 2FA on your account, you first enter your password. After that, a code is sent to your mobile device or produced by an authentication app. You must enter this code to complete the login process. This extra step makes unauthorized access much harder, as attackers would need both your password and your phone.Popular methods for receiving codes include SMS texts or authentication apps like Google Authenticator. Some users might opt for hardware security keys, which provide a physical form of identification.2FA is an important safeguard for protecting your cryptocurrency holdings from theft and hacking attempts. By implementing this additional layer of security, you significantly reduce the risk of losing access to your assets.
