USG40 - Invalid username or password.

Stellaz49

Hi. I can no longer log into my ZyXel. Its been a while since I needed to and I have LastPass so I know its the right one.

Looking through the forum it could be because my username is admin? The password is one of two, either one with a $ on the end or a 63 character string of upper and lower only.

I do not have a computer with console connection in my house and although I have a config backed up, don't really want to be messing about with a reset when everyone is home for the foreseeable.

Help and TIA.

Welcome to Zyxel community

There is a way to backup configuration file, but it need a console to do it.
