## Authentication & Key Management

The LearnCard App uses the [AuthCoordinator](/core-concepts/architecture-and-principles/auth-coordinator.md) to manage the full authentication and key derivation lifecycle. Private keys are protected using [Shamir Secret Sharing (SSS)](/core-concepts/identities-and-keys/key-management-sss.md) — 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](/core-concepts/identities-and-keys/account-recovery.md) 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](/core-concepts/identities-and-keys/cross-device-login.md) 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:

| Method              | Description                                                           |
| ------------------- | --------------------------------------------------------------------- |
| **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.
