As a multi-step registration process, two-factor authentication represents an important component of digital consumer protection. Due to the general risk situation, the BSI recommends that consumers always use 2FA if the respective online service allows this.

The Federal Association of Consumer Organizations has shown how widespread 2FA is in online services. V. (vzbv) summarized in a market overview in which over 200 digital services from 16 industries were examined. The result: Two-factor authentication options are only offered across the board in a few industry-specific areas that are already regulated. From the BSI's point of view, there is still a lot of catching up to do in order to increase the security of users in the sense of digital consumer protection.

summarized website how secure the two-factor authentication procedures offered are and what consumers should pay attention to when using them. The process evaluations prepared there are primarily aimed at consumers who already have basic knowledge of the various authentication options. Less experienced users can also find basic information about 2FA BSI website

As a conclusion of the BSI investigation, the following recommendation for action can be derived for consumers:

  • Use 2FA procedures wherever possible
  • Also use a secure procedure for recovery
  • Don't be afraid to use a process that is unfamiliar to you
  • Use multiple devices, e.g. the Push TAN app on a different device than the banking application - this is the only way the procedures can be used safely
