Passkey Insights provides comprehensive analytics about how users store and use passkeys across different authenticators and platforms.

​
Authenticator Distribution

​
Total View

View pie charts showing authenticator market share:
  • Major Authenticators (>5% share): iCloud Keychain, Google Password Manager, Windows Hello
  • Third-Party Managers: 1Password, Bitwarden, and other password managers
  • Detailed Breakdown: Complete list of all authenticators in use

​
Combined Analytics

Combine authenticator data with:
  • Operating System: See how authenticators distribute across iOS, Android, Windows, macOS
  • Browser Usage: Understand which browsers are used with each authenticator
  • Market Share Insights: Identify dominant combinations (e.g., iCloud Keychain + Safari)
The most interesting insights come from third-party password manager usage patterns. For example, 1Password usage may be highest on iOS, followed by macOS and Windows.

​
Sync Status Analysis

Track whether passkeys are synced or device-bound:
  • Synced Passkeys: Most iOS and Android passkeys via platform authenticators
  • Device-Bound: Windows Hello passkeys (as of late 2024)
  • Cross-Platform Sync: Passkeys synced via third-party managers on Windows
Monitor the percentage of Windows users with synced passkeys - these are using third-party password managers like 1Password or Bitwarden.

​
Transport Capabilities

Understanding passkey transport tags:
  • Hybrid: Passkeys that support cross-device authentication via QR code
  • Internal: Platform authenticator passkeys
  • USB/NFC: External security key support

​
Time Series Analysis

​
Trend Monitoring

Track changes over time by switching to daily/monthly views:
  • Authenticator Shifts: Monitor adoption of new authenticators
  • OS Update Impact: See how iOS/Android updates affect passkey behavior
  • Implementation Changes: Track impact of your rollout changes

​
Example Patterns

Common patterns to watch for:
  • iOS Updates: Sharp changes in transport tags after iOS releases
  • Gradual Adoption: Slow increase in third-party manager usage
  • Platform Shifts: Migration between authenticators over time
Sudden drops in hybrid/internal transport tags may indicate iOS updates or implementation issues that need investigation.
