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.

Since Plena Wallet is an account abstraction-based wallet, it already incorporates a built-in two-factor authentication (2FA) feature when users log in via social media accounts. This is part of Plena’s innovative approach to simplifying wallet access and enhancing security without requiring users to manage private keys directly. When a user logs in using platforms like Google or other social accounts, the authentication process itself serves as an additional security layer, effectively functioning as 2FA.
