2FA
What Does 2FA Mean?
2FA means "Two-Factor Authentication." It is a system that enhances security by requiring two distinct forms of identification before granting access to an online account. Unlike traditional password-only systems, 2FA combines something you know (like a password) with something you have (such as a mobile phone for receiving a verification code) or something you are (like a fingerprint). This method significantly reduces the risk of unauthorized access to accounts, as compromising two authentication factors is considerably harder for attackers. Many online platforms, including banking, social media, and email services, now offer 2FA to protect user accounts.
