# Introduction ## Understanding Passport Passport is a digital identity system designed specifically for researchers, streamlining their access to controlled biomedical datasets. By implementing [Global Alliance for Genomics & Health](https://www.ga4gh.org/) (GA4GH) authorization and identity standards, Passport enables sophisticated data sharing policies and verification of researcher credentials across multiple identities. ### Core Functions Passport manages researcher identity and access through several key capabilities: * Authentication through supported identity providers * Unification of multiple user accounts * Standardized attribution of user identities * Support for distributed access control ### Integration with DNAstack As the identity management system for DNAstack's product suite, Passport provides unified access across [Explorer](/products/explorer/introduction.md), [Publisher](/products/publisher/introduction.md) or [Workbench](/products/workbench/introduction.md). Users need a Passport account to access any of these platforms. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
