# Passkey + Enclave

Allow customers to create a native passkey on their device that is used to authenticate into a secure enclave that holds the encryption key for the user. Customers passkeys are backed up to the native cloud storage for their device.

### Implementation Requirements

1. Initialize passkey storage as a backup option in the Portal Config Object.
2. Add `portalhq.io` as a trusted credential domain in your app.
3. Share your app id with the Portal Team.
