Device Tracker Setup dumb question

This is a simple question but it has me stuck.

In the Device Tracker Setup instructions there is a section of code that should be inserted in the configuration.yaml file. It is:
‘’’
device_tracker:
- platform: net gear
host:IP_ADDRESS
username: YOUR_USERNAME
password:YOUR_PASSWORD
new_device_defaults:
track_new_devices: true
‘’’
I had to type that so the spacing may be a bit off but the simple question is: What username and password?
The router admin? (Really…?)
The router name and logon (not a username and password)
My Home Assistant ?

As I said, a simple question but it is sending me bonkers.

Many thanks
