Using App login to auto-populate user email in a form field?

If I set up my app to require the user to input their email for user login, can I have that login email address auto-populate a field in a form within that app? I am trying to set up a form that would allow employees to input daily work hours (start, time, stop time, project time, etc), and I want them to then be “Row Owners” of those data. I understand the row owner is tied to email address - it is the auto-populate of that address part I am trying to achieve.

Does this help the email question?


Seems about right.
