Can I add someone else to my admin access for my forms?

My manager would like to be able to access the forms and pull off reports periodically (I'm not always here to do that for her).

Yes, you can definitely add a sub-user to your account. The sub-user will be able to edit your forms and view the submissions.

Kindly check this detailed guide: How-to-Share-Forms-with-a-Sub-Account-User

If you have any questions, let us know. Thank you.
