We describe a prototype for inclusive and secure identity management regarding a bill sharing application in social media. Beginning with the principals of universal design, and involving groups of users with impairments, we designed a set of alternative authentication methods based on OpenID. This work explains the scenario and the particularities of designing a trust, security, and privacy infrastructure with a high degree of usability for diverse user groups, and which is aligned with the requirements from regulatory frameworks. The user trials show that several authentication alternatives in multiple modalities are welcomed by impaired users, but many have restrictions when it comes to payments in the context of social media.
