RTasks access is granted on a user-by-user basis, and can be configured to work in one of two ways for your organization:
If your users all have email addresses, these email addresses can be setup as RTasks.net usernames for your users. This is our recommended approach as it gives your users the option to reset their own RTasks.net passwords should those passwords be forgotten, as well as gives your users the option to use 2-Step Authentication(an additional security feature) when they login.
"Username" Based Login
If you prefer your users not be required to have an email address to log into RTasks, they can instead be assigned unique usernames.
