Embodiments of the invention are directed to a system, method, or computer program product for generating and using a block chain distributed network for tracking and validating a user identification morphing over time. The block chain database comprises a distributed ledger that is updated with real-time identification information including an initial identification of the user. Subsequent identifications are stored and changes or morphs in identification, such as signatures, physical attributes, or locations of the user are identified. User facts are correlated with the identifications to build a timeline for the user. Subsequently, the system generates authentication questions based off of the timeline generated. The authentication questions allow for authentication of a user into a third party system.
