@Jleput : On the assumption that you mean the WiFi pwd, Login to your MBB router at http://192.168.1.1 with username/pwd as "admin"/"admin" or with the admin password found under the battery cover. Then, if the WiFi password is not also found under the battery cover, on the WiFi Settings tab you should be able to see your WiFi password in clear & change it if you like.
