Two-factor authentication, or 2FA, is a security method that adds an extra layer of protection to your online accounts. Instead of relying only on a password, 2FA requires you to provide two different types of information to verify your identity. Typically, this means something you know (like a password) plus something you have (such as a smartphone or hardware token).
When you log in, after entering your password, you might receive a unique code via text message or an authentication app. Entering this code confirms it’s really you and helps prevent unauthorized access—even if someone else knows your password.
2FA is easy to use and highly effective. By enabling it on your important accounts—such as email, banking, or social media—you significantly reduce the risk of hacking. It’s a simple step that makes your online life safer and gives you peace of mind.
