US Patent 9817987 Restricting access to content

Various embodiments restrict or enable access to content items of an account based on login information or content request properties. For example, a synchronized online content management system can receive a request including one or more content request properties from a client device to access a user account. Access rules for the user account can be obtained and applied based on the content request properties to generate an access status. In one instance, the client device is provided with full account access if the access status indicates that the client device is an authorized device. In another instance, if the client device is an unauthorized device, at least one aspect of access to the user account is restricted.
