Two-factor authentication (2FA)

An additional security for the HU account

2FA means using a second, independent factor for authentication in addition to the usual password login as a further safeguard. Factors can be secret knowledge (e.g., password), possession (e.g., smartphone app or OTP ("one-time password") token for generating one-time passwords), or biometric attributes (e.g., fingerprint). Using two different, independent factors significantly increases the security of a person's authentication and is therefore used in particularly sensitive areas.

At HU, the second factor is implemented using TANs that employees can generate via an app on a mobile device. The HU recommended way is to install a free app on a smartphone or tablet which can then be used without an Internet or mobile network connection. Alternatively, the TANs can be generated using a hardware token, which can be requested in special cases.
