Abstract: A method and system for restricted service access is described. To access adult content, the user has to enter an administrator personal identification number into a mobile device. Upon receipt of the administrator personal identification number, an access code is generated, which is provided to a content provider. The content provider can calculate a valid time window and/or request an acknowledge message from a central server. If the current usage is within the valid time window or otherwise verified, access to the content is allowed. Thus, children are prevented from accessing adult content, while adult access is permitted.
