Two-factor, or multifactor, authentication can add a second layer of security verification when logging in to your online or mobile banking account. First, you enter your login name and password and then you have to pass a second security test.
For example, you may need to enter a special code, verify your account through an automated phone call, use biometric verification or identify an image. This makes it difficult for a hacker or identity thief to unlock your account, even if they have your online or mobile banking password.
