Read full descriptionHide full description
Client Kit is a network tool for use with the IIJ GIO Remote Access Service. This tool provides an additional authentication factor for VPN connections. Client Authentication - Client authentication is one component of two-factor authentication. It uses not only the username and password but also the unique information of the connected iPhone/iPad for authentication. - When you tap the Authenticate button, the device sends its unique information to the VPN server. The VPN server verifies whether the device information matches the information registered in advance. If the information matches, communication through the VPN server is permitted. - If no device information has been registered on the VPN server, it can be registered automatically by this tool. One Time Password - A one-time password is a password that can be used only once. - You can use the one-time password for VPN authentication when you subscribe to the Matrix Authentication option. - The one-time password is obtained from the displayed random number table using predefined locations. You must accept the license agreement below. https://www.iij.ad.jp/svcsol/agreement/pdf/GAM010.pdf
