Answering my own question, I did an experiment and tried adding a new user
(while working) and upgrading and could still log in. Based on that, I
updated my user password while working and upgraded, and it worked. So
maybe something about how the old passwords were stored/encrypted.
Anyways, that got me over the hump at least.
