If the person DOES NOT have a login enabled in your main AppColl account (non-Tandem), and you need to provide access to an already set-up Tandem account, this can be done in two ways:

1. Go to the Contacts module
2. Create a contact record with the name and valid email address (permitting it has not been created yet)
3. Next, tick the empty checkbox that is next to that record
4. Select the Enable Login button. You should see a “(number) login(s) enabled successfully” pop-up message appear and the selected contact will receive an email detailing the new username assigned along with a temporary password

From the main non-Tandem account:

1. Go to the Contacts module
2. Create a contact that contains a name and a valid email address for the person you would like to give access to a Tandem account (permitting the record has not been created yet).
3. Click the Send Invite button.
4. Select the contact record of the person who you would like to add to the Tandem account in the To field. 
5. If you would like them to have a cloned dashboard, select the account for the dashboard clone in the Clone Dashboard From field
6. Update the Subject or Body of the email as needed.
7. Click the Send button. When the new user creates their login it will automatically be linked to the existing Tandem account (as long as your account is the owner of that Tandem account).
