X-Auth is a great capability to add more security for remote users. It is possible to define the login and password of an X-Auth IPSec negotiation. If "X-Auth popup" has been selected while building the VPN Configuration, a popup window asking for a login and a password will appear each time an authentication is required to open a tunnel with the remote gateway. The end-user has few seconds to enter its login and password before X-Auth authentication fails.

Note: This time out can be configured in the VPN Configuration but it is not taken into account within the VPN Mobile.

The popup window will look like this:

In case 'Don't ask again' is selected, the login and password won't be asked each time it is required to open a tunnel. After the VPN Mobile restarts, the login and password for X-Auth authentication will be asked again.
