Two-Factor Authentication (2FA) is a security measure that enhances account protection by requiring two forms of identification before allowing access. This typically combines something you know, like a password, with something you have, such as a mobile device.In practice, when you log into an account that has 2FA enabled, you’ll first enter your password. After that, you’ll need to provide a second piece of information. This often comes in the form of a temporary code sent to your mobile phone via text, generated by an app like Google Authenticator, or provided through something like a hardware token.Using 2FA significantly increases security since even if someone steals your password, they would still need the second form of verification to access your account. This added layer of protection is particularly important for accounts that deal with significant assets, ensuring that unauthorized users cannot easily gain access.
