Netgear makes life interesting by having all manner of passwords. There is the one into the router's controls, then there are those to get into the router's wifi, and then there any that you use to get into this Community and/or MyNetgear.
Is this wifi or the browser graphical user interface (GUI)?
If the standard factory password (password) does not work, then you will have to factory reset the thing to get back to that. Then either disable password recovery (check the manual for your device) or provide some answers to those questions.
