How do I change the password on my mobile router

@Johncooter  Is this the small white mobile router?  If it is then under the battery cover there is the information you need to login to the router as an admin user to change this settings.    
 
 Have a look at THIS

Which pwd you trying to change? Admin or WiFi?

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.
