Chrome 148 introduces Immediate UI mode for passkeys and passwords, enabling websites to proactively offer saved credentials via an immediate login dialog when users click sign-in or checkout buttons. The browser silently rejects the request if no credentials are found, allowing graceful fallback to other sign-in methods. Developers migrating from the Origin Trial must update their code: the API now uses `uiMode: 'immediate'` in `navigator.credentials.get()` instead of the previous `mediation: 'immediate'`.
