Details Two-Factor Authentication (2FA)

The authentication service provides you an optional two-factor authentication.

Two-factor authentication is used to increase your security by using a second independent factor for proof of identity.

The TU Intranet Portal, opens an external URL in a new window uses a time-dependent key according to RFC 6238, opens an external URL in a new window (TOTP) in addition to the TUaccount password.

A user needs at least two of three authentication factors (proof of identity) to be successfully authenticated by an authentication server.

First factor - something I know: e.g. the combination of username and password.
Second factor - something I have: e.g. a cell phone, a security token or a smart card.
Third factor - something I am: e.g. biometric factors like fingerprint or my face.

  1. Download and install a key generator.
  2. Enable/activate two-factor authentication(2FA).

As part of the activation process, you will receive a secret code that you must transfer to the installed key generator of a personal device in the form of a QR code or string. The generator generates a new key every 30 seconds, calculated from the current time and code. For this reason, the clocks of client and server must be approximately synchronous. No internet connection is required to generate a key.

There are two ways to reset the 2FA:

1) On the website https://login.tuwien.ac.at/en/passwort/totp/, opens an external URL in a new window

Prerequisites are the TUaccount password and the time-dependent two-factor authentication key.

2) If you forget your TU password, or if you have lost the key generator or the secret code you need to activate the generator, you can deactivate the 2FA for security reasons only after a personal consultation and upon presentation of your TUcard or a valid identity card at the Service Center of TU.it, or via Teams/Teamviewer.

The key generator can be activated on several devices, if one of them fails or gets lost, a login with the remaining ones is possible. If the lost device is the only one on which the key generator is activated and the code for the generator has not been saved or written down somewhere, only the cell phone signature can be used for registration alternatively.
