SlashID Identity Management is an identity access platform that provides lifecycle management for user identities. The platform offers biometric authentication capabilities for user verification and supports PSD2 compliance requirements. The system implements adaptive, risk-based multi-factor authentication with flexible authentication factors ranging from magic links to biometrics. It provides REST APIs for importing and exporting user data to facilitate data portability. The platform supports complex user hierarchies for B2B2C and marketplace scenarios, enabling organizations and sub-organizations structures. DirectID tokens allow users to access pre-authenticated links without requiring sign-in, enabling one-tap purchases in marketing campaigns. Single sign-on functionality enables users to authenticate using third-party identity providers. The architecture is serverless and globally replicated across multiple cloud regions to handle traffic spikes and minimize latency. The platform offers native multi-region deployment through a single API to address data residency and latency requirements. User data is encrypted with individual keys derived from an HSM-backed master key to prevent mass data exfiltration. The data vault stores user information in a relational database with row-level HSM-backed encryption. The system enables anonymous user support and secure user impersonation for customer experience workflows. Risk-based authentication allows organizations to prompt for different authentication factor strengths based on operation criticality.
