Some organizations use a process called Single Sign-On where many of the applications you use every day for work are accessed through one dashboard. An example would be Office 365. Most likely, your company would have sent an email letting you know about SSO and if this is the case, please select the Login using SSO option. You will be asked to enter an email and if you do use SSO, you will be redirected to the login for your company provided dashboard where you will have an icon that can be selected to access our software. If this doesn’t apply to you then login using your username and password.
Thanks!
