Database Security Checked by Vezraa

Row Level Security (RLS)

Database-level access control that restricts which rows users can see or modify.

RLS in Supabase/PostgreSQL enforces data access at the database level. Even if your app code has a bug, RLS policies ensure users can only access their own data. Policies are written as PostgreSQL expressions and apply to all queries against the table.
