2FA is a second layer to secure your account. It can be a code generated from a security app, and SMS you receive, or specific hardware that you need to use to verify that it is you who wants to enter the account.
Unfortunately, today the right password is not a guarantee that your account is safe from unauthorized logins.
That’s why 2FA plays a vital role in hardening your account security.
Websites refer to this security feature in several different ways: two-factor authentication (or 2FA), two-step verification (or 2-Step), multi-factor authentication, and two-step authentication.
