CoachAccountable was designed to have one client account represent only one person.

The system wasn't designed to support multiple users on one account, in that there's no way for one account to have multiple email addresses or SMS text numbers, and there's no clean method to separate identities. 

There are inherent security risks to sharing any login information with more than one person; thus, we highly recommend against it.

Finally, if people end up sharing a login, you as coach won't know who did what and when with a high degree of accuracy.
