Two-factor authentication was proposed to increase the security of computer systems. From being a specialized feature of critical systems such as online baking they have increasingly been deployed in other types of less critical systems. Considering the user experiences with such security features are crucial as unsuccessful implementations can hinder access and lead to info-exclusion. Users are sometimes given choices between two-factor authentication technology to suit a given context of use considering issues such as familiarity of use, personal preferences, perceived usability, and practical accessibility. This study explores which technologies are chosen by users, and if these choices are efficient. To explore this, we designed a small experiment involving two commonly used authentication systems currently used nationally in higher education in Norway. The results showed that most participants regularly used the recommended authentication method based on Microsoft authenticator. Moreover, results suggest that this is a rational choice as the national bankID system was more than 60% slower to use than Microsoft authenticator.
