  "description": "Add Internet Identity sign-in to a frontend or canister: passkey and OpenID (Google, Apple, Microsoft) sign-in with @icp-sdk/auth, sending users to an organization's SSO with ssoDomain, the client lifecycle, and local development. Also covers the primary origin an app's principals are permanently tied to: electing it, setting derivationOrigin, the ii-alternative-origins and ii-derivation-origin documents, and the ii-app-metadata document that names the app on the sign-in screen. Use when adding sign-in, login, auth, passkeys or Internet Identity to an app, when an app gains a custom domain or a sibling app, or when the same user arrives as a different principal on two origins. For a verified email or name in the backend use user-attributes; to notify users use user-notifications; to set up an organization's own SSO use organization-sign-in. Do NOT use for wallet or ICRC signer flows (use wallet-integration) or for an agent or CLI signing in as a user (use agent-web-identity).",
