Control of website usage via online storage of restricted authentication credentials

摘要

A client communicates with a website usage server via a network to gain access to an account on a website. The client requests an indication of whether user access to the account on the website is permitted. The website usage server determines whether website usage is permitted based at least in part on a website usage policy associated with the website and the user. The website usage server provides restricted authentication credentials to the website responsive to determining that access to the account is permitted.
