Abstract: A user terminal displays on its display unit a target web page including an authentication information input field into which input authentication information is inputted by the user terminal. The user terminal judges first to third validity levels for a plurality of login history information by referring to a login information list and a service group information. The user terminal selects a corresponding process from a plurality of predetermined processes for the input authentication information based on existence or absence of the login history information in the first or second validity level and on a result of checking the input authentication information with login information in the login history information in the first to third validity levels. The user terminal executes the corresponding process.

Abstract: An entry auxiliary apparatus includes: an authentication entry detection unit, an adequacy determination unit and an entry auxiliary unit. The authentication entry detection unit detects a first authentication server URL included in data of a web page displayed. The adequacy determination unit compares the first authentication server URL with a second authentication server URL included in login information indicating an input history of authentication information and a third authentication server URL included in a service group. The service group, which includes a group of authentication server URLs locating authentication servers that authenticate with an identical authentication information, is related to the login information. The adequacy determination unit relates the login information to an adequacy level depending on a result of the comparison. The entry auxiliary unit assists input of authentication information into the web page based on the login information and the adequacy level.
