Authentication & Key Management
The LearnCard App uses the AuthCoordinator to manage the full authentication and key derivation lifecycle. Private keys are protected using Shamir Secret Sharing (SSS) — the key is split into three shares so that no single party ever holds the complete key.
Key Flows
New User Setup — After first login, a private key is generated and split into device, server, and recovery shares automatically.
Account Recovery — If a user logs in on a new device, they can recover their key using a passkey, recovery phrase, backup file, or email backup.
Cross-Device Login — Users can transfer their device share to a new device by scanning a QR code from an already-authenticated device.
Migration — Existing Web3Auth users are automatically detected and migrated to SSS.
Recovery Methods
Users are prompted to set up recovery methods after initial key setup. A persistent banner appears until at least one method is configured. Available methods:
Passkey
Hardware-bound recovery via WebAuthn PRF (Touch ID, Face ID, YubiKey)
Recovery Phrase
24-word mnemonic written down by the user
Backup File
Password-protected JSON file downloaded by the user
Email Backup
Encrypted share sent to a verified recovery email
Recovery methods are managed from the Account Recovery section in the user's profile settings.
