What is two-factor authentication (2FA)?
Two-factor authentication, often referred to as 2FA, is an authentication process which uses two layers to verify your identity. 1st Factor – Your Customer Registration Number (CRN) and password are the first-factor, or first layer of authentication used to confirm your identity. 2nd Factor – The second-factor is an additional authentication layer of security. Your Security Device provides this additional layer, and is requested each time you authorise a third-party transaction via ANZ Internet Banking for Business.
