Standard User has temporary password after migration?
I was the Administrator of our previous desktop running El Capitan, and there was one Standard User. We got a newer desktop, now running 10.15.7 Catalina. I transferred files, apps, etc. with the help of Time Machine, Migration Assistant, and "tbirdvet" (thank you!). I have the same Administrator password, and it works fine, and the Standard User intends to have her same password. During migration, we got a message saying "The Standard User has this temporary password: xxxyyy... ; write it down so it isn't forgotten." Catalina is now working pretty well, but the Standard User's temporary password is rejected when she attempts to log in with it. Any experts know what we should do next?
