Presumably you mean the wifi password. Log into the routers admin page, frequently at 192.168.1.1 or 192.168.0.1, but this may be different depending on your router. Find the wifi settings page then find the security section and change the password. This is best done with a wired connection as it will require that all wireless devices be reset to use the new password, which is of course the purpose of doing it.

If you have lost the admin password, the manufacturer has instructions on how to reset the router to its initial state with the default user name and password, usually with a reset button through a pin hole in the case. This will require the router be set up again, something that is not too difficult. Google the model of the router to see if you can find the manual, it should have specific instructions.
