What is two-step verification? Two-step verification (a.k.a. two-factor authentication, multi-factor authentication, or MFA) is a financial industry standard in which a user is required to provide additional verification after signing in. Often a verification code is provided to the user via text message or automated phone call.
Once configured, you can get verification codes without the need of a network or cellular connection. To use Google Authenticator, you need to enable 2-Step Verification on your Google Account. Visit http://www.google.com/2step to get started.
