NDAKey is a self-sovereign data management app that allows users to store digital credentials on their phones and selectively choose which information to share. Digital credentials contain user information that has been verified and digitally signed by an issuer, such as subscriber information verified by a telecommunications provider. Each credential is issued once and can be reused multiple times during its validity period at organizations connected to NDAKey. KEY FEATURES 1. Selective Sharing - Select individual information fields to share, such as full name and place of birth, without including permanent residence. - Review the data recipient's name, purpose of use, and requested information before giving consent. - Confirm each sharing request using Face ID or Touch ID. 2. Data Protection - End-to-end encryption during data transmission, ensuring that only the recipient can decrypt the data. - Digital credentials are stored on the user's device. - Passwordless sign-in using passkeys. 3. Receive and Manage Digital Credentials - Open your wallet using a chip-enabled national ID card and facial verification. - Request credentials from issuers connected to NDAKey. - Track the validity of each credential, including expired or revoked status. 4. Direct Sharing via QR Code - Scan a QR code to receive a request for information sharing. - Generate a QR code to share digital credentials or request credentials from another person in person. 5. Account Management - View the history of credential sharing, receiving, and issuance. - Manage passkeys and signed-in devices. - Delete your account directly within the app. Note: Digital credentials in NDAKey provide supplementary information and do not replace documents issued by competent government authorities. Acceptance of digital credentials depends on each data recipient.
