Two-Factor Authentication (2FA) is a security method that adds an extra layer of protection to your online accounts. In addition to your password, 2FA requires a second verification step, such as a code from a mobile app or a hardware token. This makes it much harder for hackers to gain unauthorized access, even if your password is compromised.
