i'm conducting a user testing session for a few prototypes. one of the prototypes of a feature i'll be testing is the 2 factor authentication.
Compared to other features which have more of an information or value element, 2FA seems to be a more of a security and intermediate feature.
i'd like to know what factors should i be testing for and the questions i should be asking for this feature. Some factors i'm considering are
- Does the user perceive their app environment is secure after 2FA authentication
- Ease of use for users to get authenticated with 2FA (on a scale of 1-10)
- Clarity of error messages when users encountered them
