This is completely normal. This is a macOS setting that some users prefer because it might provide more security. Do you remember the Username of your user when you were on Mojave (Or High Sierra)? If so, that is your username in the "Name" field. Password is the password to that user.

If you don't remember your creds: If you don't remember your login information, you can try using macOS Recovery to find out. First, boot macOS Recovery by restarting and pressing Command + R. Next, access the Terminal. If you had your disk encrypted, then first, you would need to type diskutil unlockVolume diskID and type the password of the disk. Then, type diskutil mount diskID. Then, you can do cd /Volumes/VolName/Users and ls. This will show you all users on the Mac.

Good Luck!

  • You can check by seeing if there are 2 Macintosh HDs. Also, for future issues, you can also try using sudo dscl . -create from Single User Mode to create a new user.

  • Well actually, having two instances of macOS means that you have two disks with one instance each. That might tell you if you have two instances of macOS. The sudo dscl . -create was a suggestion should you run into the problem again.

https://apple.stackexchange.com/a/324521/371580 This helped me alot. If you resintalled on existed Mac OS most probably setup assistant will not show up. If this was the problem Delete .setupassistantdone from recovery terminal search for it and delete it then everything will be okay. Find more details with steps in this answer
