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.
Different passwords pop up at different times, depending on how you connect to the device and where you are trying to access from, your local network or somewhere else on the Internet. (Previously known as Remote Access, that's now called Anywhere Access.)
If you are talking about access to the browser's graphical user interface (GUI), the router's controls, these are on the label for your device, along with the default wifi login details.. The username is fixed at admin. The default password is password.
If you are trying to use the "password recovery" option, there is a bug in Netgear's implementation of password recovery on some devices. You can get locked into a closed loop.
If password recovery is enabled, but you have not set the answers to the questions, it keeps sending you back to the beginning of the process. If you haven't already given the thing your personal answers, they are not in its memory and it has no way of knowing if they are correct.
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.
