# Self-Sovereign Identity Self-Sovereign Identity (SSI) is a decentralised model of managing one's identity that gives users agency over their data. SSI allows people to interact in the digital world with the same freedom and capacity for trust as offline, reducing the need for intermediaries. Unlike traditional models where central authorities, such as governments or corporations, store and manage our personal information, SSI affords users more control over their data and the management of its revocation. Users no longer need to give up control of personal information to dozens of databases to access new goods and services, with the risk of their identity being stolen by hackers or third parties using their data for other purposes. With SSI, individuals can host their own digital identity that can then be used to interact with other entities securely and privately, sharing what is necessary and attesting to their identity verification. --- # 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.
