My experience with Meta is it is just a PII fishing expedition masquerading as a security check.

I abandoned my facebook account when they asked for my driver's license scan, a few weeks later suddenly they didn't need it after all. My BIL recently wanted me to check sout omething he had setup on facebook and I found I could "login" by clicking one of the "what are people doing" spam emails they send. I've never used it on this PC before and have no idea what the password even is anymore. Super secure.
