User registration and questionnaire management for club

I run a WordPress based website for a sports club. Due to current COVID-19 restrictions every member must fill out a form answering Covid related questions before they come to every training session. This is currently done using paper.

I would like to move this process online however, I’m not sure how to achieve this.

I was thinking of getting every user to register for an account on the website and then have them complete the form electronically.

Every member has a membership number. Is there a way they could register by putting in the membership number and making a password? This way I wouldn’t have to make all the accounts myself and not everyone can register, only people with an membership number.

I also do not know how to make a form for each user. I would have to be able to keep track of who has completed the form and who hasn’t.

If anyone can help I’d really appreciate it.
