Add admin password?

I installed yacy abotu 2 months ago, then when rebooting the server, yacy stoppe working altogether. It would not run any more.

That’s fine, right? So, I created a new server for yacy to run on. I installed it. It runs fine.

It worked form the same server, I opened port 8090, and it truns.

I tried running from my PC to use it.

It needs a password.

I do nto have one. I use the script to TRY and make one.

It ask for new PW, I enter it.
It asks for host admin PW, I have no idea what this is? I entered the server log in password(Linux MINT has no admin user) for yacy server.
It failed.

I go back to the yacy server, and for anything I want to do, it now needs a password.

How do I set a password? There needs to be a way to do this for the local host interface. The passwd script does not work.

What is the default password?
