How to login without password for demo on my VDS/VPS?

I have installed Home Assistant on my server on the internet. And I would like visitors to be able to view and click on the interface. This setup is for demonstration purposes only. I made special beautiful cards and automation there.
How to make it so that there is no window for entering a password?
I want the user to be able to immediately study this wonderful system - Hom Assistant and my achievements.
I want to advertise my smart home services on my website.
