Abstract

An information processing apparatus is provided. The information processing apparatus has a power-saving function for changing a mode of the information processing apparatus from a normal mode to a power-saving mode in which a power consumption amount is smaller. When a predetermined condition is satisfied, the apparatus obtains an access token and an expiration time of the access token from the authorization server, stores an expiration time of an obtained access token and the access token in association with each other, and returns, if the information processing apparatus is in the power-saving mode, to the normal mode and updating at least some of obtained and stored access tokens when an expiration time of at least one access token out of the obtained and stored access tokens is reached.
