Identification


Project Links


Description

Identification is a Self product that integrates identity-verification flows into mobile applications through Android and iOS SDKs. It supports email addresses, passports, ID cards, and driving licences; verified credentials are stored locally on the user's device and can be presented to relying parties. Self also documents cryptographic signatures, decentralized identifiers, verifiable credentials, and privacy-preserving verification.

Authentication


Project Links


Description

Authentication is a Self product concept comprising prototype tools for developers, with documentation, SDKs, examples, and embedded integration options. It uses biometrically gated, non-correlatable identifiers and can support authentication without an organization holding personally identifiable information; exchanges may also carry identity and verifiable-credential payloads. The site states that the prototypes may break.
