Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) is a security process that adds an extra layer of protection to user accounts by requiring two forms of verification. In addition to a password, 2FA typically involves a second factor, such as a one-time code sent to a mobile device, a hardware token, or biometric verification (e.g., fingerprint or facial recognition). This additional step enhances security by ensuring that even if a password is compromised, unauthorized access to the account is still prevented.

In the cryptocurrency space, 2FA is commonly used to secure accounts on exchanges, wallets, and other platforms that manage digital assets. By implementing 2FA, users can protect their funds from hacking attempts, phishing attacks, and other forms of cybercrime. Popular methods of 2FA include SMS codes, Google Authenticator, and hardware-based solutions like YubiKey. Users are encouraged to enable 2FA on all their cryptocurrency accounts to minimize the risk of unauthorized access.
