I get those too. You know now that that was a phishing attack, right? It was not from Apple--they don't do that. In the future, just delete those emails without clicking on any links.I was one of the lucky people whose Apple ID was "locked for security reasons."
I have booted up with a with a ATI 5770
reenabled SIP
restarted
Now the computer attempts to unlock with the watch but falls back to the keyboard entry.
