Very narrow space to set up quiz pass and fail reports
Why is the message window not wide enough? The width cannot be adjusted.
How should I do it?

Could you pls share the URL of this page on your site so I can check? as I can't replicate this at my end.

The login information for teachers is the same as for logging in to the administration, I mentioned it in my other questions. However, you have also created your own access to the teacher's administration:
test teacher
testteacher@test.com
I don't know the password you entered.

I added this custom CSS into your site to enlarge the form, kindly check.
