How do operating system versions impact passkey compatibility?

Operating system versions are crucial in determining passkey compatibility. Here’s why:

1. Recent OS Versions:

   • Most modern operating systems support passkeys:
     • iOS 15+ enables passkeys in Safari and other browsers.
     • Android 12+ supports passkeys through Chrome.
     • Windows 11 supports passkeys via Windows Hello (requires activation).

2. Older OS Versions: Outdated OS versions may lack passkey support, which could limit adoption rates for users on older devices.

3. Platform Authenticator Guidance: On compatible OS versions, users are often guided to enable features like Touch ID, Face ID, or Windows Hello during passkey setup.

Understanding the role of OS versions allows enterprises to anticipate compatibility issues and improve the adoption of passkeys across their user base.
