Compatibility reality check

Passkeys are mature across major platforms, but reliability depends on updated OS, browser support, and authenticator sync health.

  • iOS/iPadOS: keep iCloud Keychain and your Apple account security features enabled so passkeys can sync normally.
  • Android: use the same credential provider or account context and keep device security enabled before relying on synced passkeys.
  • Windows: configure Windows Hello before relying on platform passkeys in supported browsers.
  • Cross-device QR flows usually depend on Bluetooth proximity and camera permissions.
