Role-Based Access with RLS and Custom Claims

Build advanced Row-Level Security policies that grant different access by user role using JWT claims and helper functions.

Beyond Owner-Only Policies

Basic RLS often checks auth.uid() for ownership. Real apps also need role-based rules, like admins seeing everything and editors seeing more than viewers.

Where Roles Live

You can store roles in a column on a profiles table, or embed them as custom claims in the user's JWT for fast, joinless checks.
