Public Vs Private computer settings (vNet Portal)

If you connect to the vNet Portal site from a public computer, such as a kiosk computer in a public establishment, or from a computer that you share with other users, click This is a public or shared computer. You will need to provide both your user name and password each time you sign in to the RD Web Access website.

If you're using a work computer assigned to you, that you don't share with other people, click This is a private computer. Your user name will be remembered, so you'll only have to provide your password each time you sign in to the RD Web Access website.

To protect against unauthorized access, vNet Web Access sessions automatically end after a period of inactivity. If your vNet Web Access session ends, you'll need to sign in again. The amount of time before a session ends is determined by your administrator.
