The UK's National Cyber Security Centre (NCSC) has updated its official guidance to recommend passkeys as the default authentication method for consumers and businesses, replacing traditional passwords. Passkeys provide superior resilience against modern cyber threats, particularly phishing and credential theft, while offering a faster, more user-friendly login experience.
This architectural analysis details the hidden mechanisms behind Google's synced passkeys, revealing a hybrid model that leverages a cloud-based authenticator (enclave.ua5v[.]com) for sensitive cryptographic operations while anchoring trust to local hardware keys. Understanding this infrastructure is critical for defenders to anticipate emerging attack vectors in passwordless authentication environments.
