For example, VPN connections are commonly used by corporations and educational institutions for users who need to access intranets and other internal services when they are outside of the internal network, for example, when they are traveling. VPN connections can be set up in many ways, depending on the network. Some networks may require you to transfer and install a security certificate on your device. For detailed information about how to set up a connection to your virtual private network, contact the network administrator of your company or organization. If you are using a device with multiple users, you may need to log in as the owner, that is, the primary user, to adjust the settings for VPN. 51 This is an Internet version of this publication. © Print only for private use.
