When you are MANUALLY entering caregivers into your system, BlueSky DOES NOT generate a notification email to your Caregivers. It is not until you generate a User Id and Password and click the "Login Allowed" button that they will be able to log in (pictured below) themselves.
Once you generate that login information, it is YOUR RESPONSIBILITY to send that login information to the caregiver. When they log in for the first time, they will automatically get a Security Request telling them that the Company assigned their password, and that it must be changed (pictured below).
The caregiver then creates his/her new password and can log in from here.
