MyDid is a company based in Switzerland that empowers users to regain control over their digital lives by managing multiple Decentralized Identities (DIDs) that are created, owned, and operated by the users themselves. With the help of MyDid's Decentralized Application, users can manage their personal data by creating a Decentralized Identity, collecting open badges and verifiable credentials, presenting them as Verifiable Attestations when required, and revoking them as necessary. All private data is securely stored locally and protected through cryptography. Users have complete control over their credentials and do not depend on any third party for their integrity. MyDid fully adheres to the W3C specifications for DIDs and incorporates the latest standards for Verifiable Credentials and Open Badges. The company has also developed its own DID method called Secured Digital Identity (SDI) and resolver architecture, which represents the cutting-edge technology in this field. By utilizing MyDid, users can exercise full control over their personal information, deciding whether to share, hide, or revoke access to it, while maintaining a record of all consents and shared data.
