We recommend adding a default admin to your Ditto account in the event the account owner leaves your school or organization. This will prevent the loss of access to your account in the case of there only being one admin for the account. The default admin can be a generic "IT@" email address or an email address that can be accessed by any user in your school or company.
You can follow the instructions in the links below to add or delete users from your Ditto account.
