FinanzOnline sets the standard: mandatory 2-factor authentication from October!

From October 1, 2025, the FinanzOnline platform will introduce mandatory two-factor authentication (2FA) in Austria. This measure aims to significantly increase the security of the platform and was described as an international model solution by Finance Minister Markus Marterbauer. According to the new regulations, it is still possible to contact the tax office offline and handle tax matters using forms. The introduction of 2FA is based on proven security standards that are already established in the banking industry to strengthen user trust and provide better protection against digital threats. Gailtal Journal reports on these significant changes.

Two-factor authentication is a proven method for increasing the security of online accounts. It requires not only a username and password, but also an additional authentication step provided by a separate transmission channel. Loud Onlinesicherheit.gv.at Various methods can be used for authentication, including knowledge (e.g. password), possession (e.g. ATM card) and biometric features (e.g. fingerprint). This provides additional protection for sensitive data in times of increasing cyber threats such as phishing and malware attacks.

Restoring 2FA

The 2FA can, as in BMF.gv.at mentioned, can also be restored if users forget their login details or lose the recovery code. If the recovery code is present, recovery is quite simple: After logging in to FinanzOnline, the user can enter the recovery code to reset authentication and register a new device.

However, if the recovery code is lost, users must go to the FinanzOnline login page and select the “Forgotten or blocked password” option. You will need to enter your social security number, an official photo ID and your user name. After the successful reset, an initial password is provided with which the user can log in again and set up 2FA again.

Benefits of two-factor authentication

The introduction of 2FA at FinanzOnline is a further step towards improved data security. One-time passwords (OTPs) and token-based authentication are among the common methods that can be used in this context. An example of this is the use of an ATM card (possession) in combination with a PIN (knowledge) for cash withdrawals, such as Onlinesicherheit.gv.at describes.

By implementing 2FA, the Ministry of Finance sees a clear improvement in security for FinanzOnline users. However, users must weigh the additional effort involved. Nevertheless, this measure could prove indispensable to address digital security challenges and better protect personal data.
