Cannot Access Superadministrator account [removed google oauth credentials]

Cannot Access Superadministrator account [removed google oauth credentials]

Created a zoho mail account for a friend but accidentally used my google oauth to create the account and log in. I didn't want my name or google account attached, so once I logged in I made my friend the superadministrator with the email address that I just created for him on zoho and removed my own google credentials from the profile. The problem is Zoho never asked me to create a new password for my friend so essentially he has a superadministrator account that no one can log into since I removed my google credentials from the profile. Would it be possible for zoho to set up a default password so that we can access the account? I hope this makes sense...
