This Web Platform feature enables issuing websites (e.g., a university, government agency, or bank) to securely initiate the provisioning (issuance) process of digital credentials directly into a user's mobile wallet application. On Android, this capability leverages the Android IdentityCredential CredMan system (Credential Manager). On Desktop, it leverages cross-device approaches using the CTAP protocol similar to Digital Credentials presentation.
Without this, websites and wallets can only communicate in ways that are more opaque to the browser and OS.
