Need help with ECR in Joomla 6

ECR installed and acivated in Joomla! 6.
However, having issue with attempts to get "password mode" working.
Questions:
What code do we enter to use "password mode" when no J!6 user account needed to load article, just the password.
We need to password protect with inidividual passwords, several articles on the Joomla! 6 website.
Where do we put this code to make it work.
Assistance is needed ... please.
