Reset password

Zyxel USG40
This morning the system asked me to change password.
I changed the password at the login screen, but something must have gone wrong.
After a firewall reboot I can't login any more.
Found a lot of solutions where people connected to the device with a serial cable to reset the password.
This firewall only have an RJ45 Console port, how to I connect to that port with putty ?
Do i need a serial to RJ45 cable or...
Is the console port a network port I can connect to ?
Can't find any info on it online.
I would be very sorry to reset the box totally, cause I don't have a backup of the config file.
Any hints ?

I have ordered a Console Cable RJ45->USBC cable, hope that do the trick for me.0

I did not use Console Cable RJ45->USBC cable before.
My console able is: USB -> RS232 -> RJ45
But I guess it is the same.0 -
We are using a RS232 cable + USB adapter.In past we experienced this "password reset" issue, too. At that time the USG was not able to use every special character for passwords. We've set a new complex one and were not able to login again. But I guess, this should be solved in the meantime.But by the way Bilglasgruppen, there is a saying in IT business: "No backup, no sympathy."Please, after your device is running again, save your configuration file. This will save your ass different times.0
