3.2. Multi-factor authentication

What multi-factor authentication means

A newer and more secure method of logging in is multi-factor authentication. In multi-factor authentication, you have to authenticate several times in different ways and different transmission channels are used for this purpose. It is also called two-factor authentication (2FA), but it basically always follows the same principle: it adds an additional authentication step to logins that require username (identification) and password (authentication), such as entering a TAN or verifying a biometric feature like fingerprint or facial recognition. The key thing is that a separate transmission channel is used for this.
