American tech giant Google has expanded the capabilities of its Password Manager by enabling the syncing of passkeys across multiple platforms, enhancing the tool’s cross-device functionality.

Previously, passkeys were only saved on Android devices, limiting their use outside the platform, as per a report by Microsoft Start.

Under the old system, users who wanted to access passkeys on non-Android devices had to scan a QR code, creating extra steps for cross-device usage.

New cross-platform support

With the latest update, passkeys can now be saved and synced through Google Password Manager across a broader range of operating systems, including:

Windows
macOS
Linux

This update is in addition to Android devices, while ChromeOS support is currently undergoing beta testing. iOS compatibility is also expected to roll out soon, expanding Google's reach further.

Automatic syncing and enhanced security

Once saved, passkeys are automatically synced across all supported devices via Google Password Manager, ensuring a seamless user experience. To address security concerns, Google emphasized that all passkey data is end-to-end encrypted, providing robust protection against unauthorized access.

Passkeys differ from traditional passwords, serving as digital credentials that allow users to sign in to their accounts without needing a password. This development aligns with Google's push for stronger security measures, having integrated passkeys into its software suite since 2023.

Additionally, the new update introduces an extra layer of security. Users will now be prompted to set a six-digit PIN when utilizing passkeys on a new device, further fortifying the authentication process.
