<p>An access point 11 for enabling user device to access a data network, the access point 11 wirelessly communicating with the user device and providing data network access for the device when authenticated. The access point 11 includes authentication means 64 and processing means 48 for providing an authentication code for transmission to the user device to enable the user device to be authenticated for a communication session with the access point 11 by the authentication means 64. The processing means 48 may generate an authentication code to authenticate the user device with the access point 11 for a predetermined number of times, e.g. only once, or to authenticate the user device with the access point 11 until a predetermined time. The authentication code may be provided to the user device by a printed medium or sent by wireless communication, such as SMS. The access point 11 may include means for determining when the authentication code expires and interrupting the data network access in dependence thereon.</p> |
