When you create a new user in the WorkSpaces Applications user pool, or assign a user pool user to an WorkSpaces Applications stack, WorkSpaces Applications sends email to users on your behalf. Users enter the URL that was provided to them in the welcome email, enter their credentials, and then choose **Connect**.
