Question:
Multifactor authentication (MFA) is used if more than one authentication method is required. In this case, biometrics are used, although the passcode itself is not a biometric factor. As part of multifactor authentication, an authenticator app can generate a code. The unique key provided by authenticator apps, which run on devices like smartphones and PCs, changes every few seconds. The key serves as evidence that you actually own the smartphone or PC. A TPM chip, which prevents access to a drive if the chip is not there, or a feature like Microsoft's BitLocker, which encrypts an entire drive's including the boot files, could be used to achieve full-device encryption. Two of the following four types of inputs are often required for multifactor authentication: something you know (password), something you have (smart token), something you are (biometrics), or somewhere you are (GPS or other location services).
