If you have been assigned Authorized User permissions, you can login as another user you are linked to see. From the top right menu, click your profile image.
User Profile options will display. Select Login As Another User.
Every user you have permission to login as will display in the grid. Click Login as [name] to select one.
You may now see and do everything your selected user has access to do. The only exception is that you will not be able to view the other user's My Reports.
You can see that you are logged in as someone else at the top right. Click the white X to return to your own dashboard.
