What is Two Factor Authentication (2FA)?

Two Factor Authentication (2FA) is a security mechanism to enhance the security level of user authentication by using one more factor. Traditionally, 2FA uses two out of three types of factors before accessing the services. The three types are:
1) Something you know, such as password or passphase
2) Something you have, such as phone or token
3) Something you are, such as biometric like a fingerprint or voice print

One-Time Password is the second authentication method of 2FA service. VTC staff can receive One-Time Password for authentication by Mobile Application or SMS message.
