The process for changing your router's password depends if it is a NOW router or not.
If your router was supplied by NOW:
You will need to give us a call on 0800 GET NOW (0800 438 669) or email us at email@example.com
We can remotely configure your password for you.
If you provided your own router:
Unfortunately we will not have access to your router, so we would be unable to complete this for you.
Changing the WiFi password is usually completed by accessing the router's administrative settings.
If you are unsure on how to do this, please consult your router's manual.
