That is one "out of band" authentication mechanism called TOFU (trust on
first use) or LOF (Leap of Faith)

While possible, it will see a lot of false positives, like when going to

It could be done if one also logs mac address and/or lat/long info.

But these are all local policy and local implementations issues.
