The sequence begins on a desktop machine with an attempt to generate a passkey, where it immediately becomes apparent that LastPass lacks support for the required Pseudo-Random Function extension and cannot handle the encryption requirement.

To work around this initial limitation, the effort shifts to a handset on the same local area network, aiming to establish the passkey in Google Password Manager instead. This introduces the cross-device protocol, which ignores the functional network connection and mandates a Bluetooth Low Energy proximity check. Because the desktop hardware cannot broadcast the required beacon, the local handshake silently fails. This results in a timeout on the handset and a vague error on the desktop Chrome browser, deliberately obscuring the hardware incompatibility behind a privacy standard.

After pushing through the broken state management and eventually registering the passkey on the Android device, the process returns to the desktop to log in. At this point, LastPass aggressively intervenes again. Despite its established inability to process the passkey, the extension pounces on the credential request, acting as an absolute block that prevents any capable handler from stepping in.

Once the LastPass extension is manually disabled to clear the path, the expectation is that Google Password Manager will finally supply the credential. Instead, a Windows Security prompt abruptly takes over the screen. Google Password Manager fails to respond because the newly created passkey has not yet synchronised to the local desktop browser profile. In the absence of an immediate local credential, the operating system forcefully hijacks the process, demanding a hardware security key or another cross-device scan, trapping the attempt in a final dead end.
