Google on Thursday unveiled a Password Manager PIN to let Chrome web users sync their passkeys across Windows, macOS, Linux, ChromeOS, and Android devices. This PIN adds an additional layer of security to ensure your passkeys are end-to-end encrypted and can't be accessed by anyone, not even Google, The PIN is a six-digit code by default, although it's also possible to create a longer alpha-numeric PIN by selecting PIN options. This marks a change from the previous status quo where users could only save passkeys to save passkeys to Google Password Manager on Android. While the passkeys could be used on other platforms, it was necessary to scan a QR code using the device where they were generated.
