If I have 3 dashboard, should I have different user role or different user type

First of all, it seems they would have different roles if it's three different dashboards. And second naturally you would need different authorization which user can use which dashboard so yes you would need either Gates of policies in conjunction with dashboard usage.

I have something similar I have admin area and bookkeeping area.

Do you use role or just setup up entirely new guarding for different users type?

I think better will be if you use just roles.

Just remember:

RBAC is at least 3 main steps:

• A login required
• An authorization implementation to determine what the logged in person with role can or cannot do
• Protection of URL and parameters, checking that the logged in users id matches the id used in a query Each application will require unique tweaks in RBAC, no two apps are exactly the same.

Query Scopes can be used to differentiate an admin from a user, and what data is shown in the query.

But of course if you want to use 3 dashboards with role only that's your choice.
