The invention relates to a system comprising a network device (NSC), a host computer (HOST) and a remote server remote (SRV). The host computer (HOST) and the network device (NSC) server are connectable through a network. The host computer (HOST) and the remote server (SRV) are connectable through the Internet. The smart network device (NSC) comprises a web server accessible from the host computer (HOST). The network device (NSC) is set to store a user's authentication credential. The host computer (HOST) is set to display a web page produced by the remote server (SRV) to the user. The remote server (SRV) is set to include a login link in said web page, the login link pointing to said web server. The web server is set to display a login page to the user on the host computer (HOST) when the user clicks on said login link, in order to authenticate the user. Upon authentication of the user, the network device (NSC) is set to send the user's authentication credential to the remote server (SRV) in order to authenticate the user to the remote server (SRV).
