This document discusses Bring Your Own Identity (BYOID) using the WSO2 Identity Server. It provides background on WSO2 and describes how BYOID is driven by trends like social network integration and user fatigue with multiple identities. The WSO2 Identity Server supports key identity standards including SAML, OAuth, OpenID Connect and can mediate between different identity tokens to enable BYOID across different systems and protocols. Two scenarios demonstrate BYOID workflows between operators and service providers using various identity standards.
