Supabase row level security isolates multi-tenant data by defining fine-grained RLS policies that enforce tenant isolation and ownership rules. You create policies restricting access based on tenant identifiers, ensuring users only query and modify their own tenant's records.

Database schema migrations in Supabase should be handled by defining structured migration scripts that apply normalization and constraints. This ensures smooth schema evolution for applications, maintaining data integrity across table structures as your multi-tenant application scales.

Data encryption for sensitive fields in Supabase works by applying encryption mechanisms to specific columns and outlining key management strategies. This secures regulated data lifecycles, such as encrypted API key handling, protecting sensitive information stored in the database.

Yes, you can enforce role-based access control in Supabase by defining RLS policies that map user roles to specific data access permissions. This approach secures data access across multi-tenant applications by restricting queries and mutations according to role hierarchies.

You need RLS policies for your Supabase database schema whenever building multi-tenant applications or handling regulated data contexts. They are essential for enforcing tenant isolation, implementing auditable access, and securing sensitive data lifecycles across your application.
