Overview
When authenticating from a Windows 11 machine, if the browser used for authentication is Firefox, the Okta Verify push notification will report the OS as Windows 10.

Example System Log Event:
Applies To
- Okta Verify Push
- Firefox
- Authentication
Cause
As per Microsoft's documentation, this behavior is expected. In Microsoft Edge (and also in Google Chrome), sites can differentiate between users on Windows 11 and Windows 10 and can detect the device's CPU architecture via User-Agent Client Hints (UA-CH).
Firefox does not support the CH header and only uses the user agent string.
Solution
There is no immediate solution apart from using a different browser, like Chrome or Edge.
