8.1.3 Summary of Usability Considerations

Figure 3 summarizes the usability considerations for typical usage and intermittent events for each authenticator type. Many of the usability considerations for typical usage apply to most of the authenticator types, as demonstrated in the rows. The table highlights common and divergent usability characteristics across the authenticator types. Each column allows readers to easily identify the usability attributes to address for each authenticator. Depending on the users’ goals and context of use, certain attributes may be valued over others. Whenever possible, provide alternative authenticator types, and allow users to choose between them.

Multi-factor authenticators (e.g., multi-factor OTPs) also inherit their activation factor’s usability considerations. As biometrics are only allowed as an activation factor in multi-factor authentication solutions, usability considerations for biometrics are not included in Fig. 3 and are discussed in Sec. 8.1.4.
