# How does Cloud Sync function across different platforms?

Bullbit encourages utilizing the built-in sync features provided by manufacturers:

1. Apple (iOS/macOS): If you enable iCloud Keychain, a Passkey created on an iPhone will automatically be available on your MacBook or iPad (provided they share the same iCloud account). You only need a TouchID scan on the Mac for instant access.
2. Google (Android/Chrome): Bullbit uses Google's On-device encryption. Passkeys created on Android will automatically sync to the Chrome browser on your computer if you are logged in to the same Google account with Sync enabled.
