Designing Supabase authentication for multi-tenant workspaces involves defining actors, user records, and profile ownership, then mapping role-based permissions across team memberships, invitations, and workspaces. It enforces integration with Supabase Auth and backend logic to manage access control across deployments.

The best way to manage authorization checks is to identify which permissions live in Supabase Row Level Security (RLS) policies and which require backend logic enforcement. This split ensures scalable access control by mapping auth events to schema implications and enforcing backend requirements for complex membership flows.

Setting up Supabase auth invitations for a SaaS application requires defining a specific invitation model and deciding how users join teams or workspaces. You must map these membership flows to auth events, schema policies, and sign-in methods to ensure proper user identity and access control.

Supabase auth supports custom sign-in methods and session management by defining actors, user record strategies, and profile ownership. It maps auth events to schema and policy implications, ensuring scalable access control through RLS coverage and backend enforcement requirements.

You should not use Supabase RLS for authorization when access control checks require complex backend logic beyond row-level visibility. The architecture requires identifying which specific authorization checks need backend enforcement instead of RLS to properly handle team memberships and role-based permissions.
