Welcome! Hopefully you will have a great time with Tryton.
There is a special module which is covered behind the curtains because maybe some people will install that module unattended and basically open there production server to the rest of the world. So it’s a big security risk to have this module in the default repositories. So please be careful about this module!
That said. You have to build the module yourself, which is not a big deal. I don’t know your instance, but imagine you have done it with a virtual environment do the following steps:
If you are using a container, you can also look at tryton-docker-demo: log I don’t know if this demo container is published. But you can build it yourself.
Yes, you have to modify your configuration file to tell Tryton which authentication method(s) can be used.
So take a look at Configuration file for Tryton — Tryton server and specific Configuration file for Tryton — Tryton server where is explained how you can add the different authentications (don’t skip the first link if you don’t know what the configuration file is).
In your case it would be something like authentications = none,password
