Create a dummy email. Create an email address in Google—or use an existing one—and share the password and username with your admin. This email address is effectively a "dummy" that both you and your admin will use to login to your Reclaim account.
Connect the dummy email to your Reclaim account. Go to Settings -> Accounts and add the "dummy" email by clicking Add another account.
Collaborate! Your admin can log in to your Reclaim account using the dummy email so they can create and manage your Habits, Tasks, Sync Policies, Smart 1:1s and so on.
