INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

1 . An information processing apparatus comprising:

a memory configured to store, in an associated form, management information and a refresh token, the management information associated with a user, the refresh token serving as second qualification information that is used to acquire an access token serving as first qualification information for use of a web service; and

a processor configured to

accept the management information,

transmit to an authentication server the refresh token associated with the accepted management information and stored on the memory,

receive the access token that is transmitted from the authentication server if the authentication server has verified that the transmitted refresh token is effective, and

use the web service with the received access token.

2 . The information processing apparatus according to claim 1 , wherein the processor is further configured to,

if the refresh token associated with the accepted management information is not stored on the memory, cause a display to display a screen that requests the user to enter authentication information for the authentication server to authenticate the user,

accept the authentication information,

transmit the accepted authentication information to the authentication server,

receive the access token and the refresh token that are transmitted by the authentication server if the authentication server has successfully authenticated the user in accordance with the transmitted authentication information,

cause the memory to store in an associated form the accepted management information, the accepted authentication information, and the refresh token received from the authentication server, and

use the web service with the access token received from the authentication server.

3 . The information processing apparatus according to claim 1 , wherein the processor is further configured to delete the access token from the information processing apparatus if the user has logged out from the information processing apparatus.

4 . The information processing apparatus according to claim 2 , wherein the processor is further configured to delete the access token from the information processing apparatus if the user has logged out from the information processing apparatus.

5 . The information processing apparatus according to claim 1 ,

wherein the authentication server issues an access token on a per web service basis to use the web service, and

wherein the processor is further configured to

transmit to the authentication server the refresh token and information to identify the web service specified by the user,

receive the access token that is for use of the web service specified by the user and is transmitted by the authentication server if the authentication server has verified that the transmitted refresh token is effective, and

use the web service, specified by the user, with the received access token.

6 . An information processing system comprising:

an information processing apparatus; and

an authentication server,

wherein the information processing apparatus includes a first memory and a first processor and the authentication server includes a second processor,

wherein the first memory stores, in an associated form, management information and a refresh token, the management information associated with a user, the refresh token serving as second qualification information that is used to acquire an access token serving as first qualification information for use of a web service;

wherein the first processor is configured to

accept the management information, and

transmit to the authentication server the refresh token associated with the accepted management information and stored on the first memory,

wherein the second processor is configured to

receive the refresh token transmitted from the information processing apparatus,

verify effectiveness of the received refresh token, and

if the received refresh token is effective, transmit the access token to the information processing apparatus, and

wherein the first processor is further configured to

receive the access token transmitted from the authentication server, and

use the web service with the received access token.

7 . A non-transitory computer readable medium storing a program causing a computer to execute a process for processing information, the computer including a memory storing, in an associated form, management information and a refresh token, the management information associated with a user, the refresh token serving as second qualification information that is used to acquire an access token serving as first qualification information for use of a web service, the process comprising:

accepting the management information;

transmitting to an authentication server the refresh token associated with the accepted management information and stored on the memory;

receiving the access token that is transmitted by the authentication server if the authentication server has verified that the transmitted refresh token is effective; and

using the web service with the received access token.
