Abstract: OpenID is an open and promising Web single sign-on (SSO) solution. This work investigates the challenges and concerns web users face when using OpenID for authentication, and identifies what changes in the login flow could improve the users' experience and adoption incentives. We found our participants had several behaviors, concerns, and misconceptions that hinder the OpenID adoption process: (1) their existing password management strategies reduce the perceived usefulness of SSO; (2) many (26%) expressed concerns with single-point-of-failure related issues; (3) most (71%) held the incorrect belief that the OpenID credentials are being given to the content providers; (4) half exhibited an inability to distinguish a fake Google login form, even when prompted; (5) many (40%) were hesitant to consent to the release of their personal profile information; and (6) many (36%) expressed concern with the use of SSO on websites that contain valuable personal information or, conversely, are not trustworthy. We also found that with an improved affordance and privacy control, more than 60% of study participants would use Web SSO solutions on the websites they trust.
