Upgrading to a new router

I just upgraded to a new Fios router.  I have had the old Fios router for about six years.  I'm getting ready to switch it out but I have a question about the old wifi ID and password versus the new router id and password. Will I need to change my password on every phone, tablet, hue light, etc to the new password on the new router or is there a way to just set up the new router and have everything stay the same?  Any help is greatly appreciated.

Thanks!
