Hi,
It is fine to change the default user template, that is why odoo added this option under general settings.

* Open settings
* Search "Default Access Rights" in the search box and click the navigation button

Now you can change the default access rights as per your need. This can be done from the user interface as well as from the code depending on your need.

Thanks

Thank you guys so much, this is important to me

Hi,

In odoo you can customize any template or record by inheriting them. To customise default user template, you need to check the record id of that corresponding record. And inherit it in your custom module.Please refer the below documentation of view inheritance

And also you can refer the below blog to know on modifying existing record rules in odoo

Hope it helps

Probably yes, because otherwise new users will have too much access (by default).

This only indirectly sets record rules - it's the user access groups for each user that control access.  

Customizing record rules is more complex
