Supabase authentication manages user sessions and multi-factor authentication through built-in auth flows. Configure auth policies in your client, handle session tokens securely, and enable MFA via the dashboard or API to meet production security requirements.

Row Level Security (RLS) policies control database access at the row level using PostgreSQL rules. Define RLS policies in Supabase to restrict queries based on user identity, then attach them to tables to enforce data isolation across authenticated and anonymous users.

Supabase real-time subscriptions work with Next.js, React, Vue, Svelte, and server-side environments. Listen to database changes, storage events, and presence updates using the Supabase client library integrated into your framework.

Supabase storage provides file upload, retrieval, and CDN delivery for static assets and user files. Set up storage buckets, define access policies, and configure CDN to serve files at scale with security policies enforced per bucket.

Supabase AI features enable vector embeddings and semantic search using PostgreSQL extensions. Store embeddings as vectors, query by similarity to find semantically related content, and integrate AI capabilities into your application workflow.

Production Supabase deployments require TypeScript-first code, error handling, performance optimization, and testing strategies. Use type safety for database queries and API calls, test RLS policies, and monitor edge function execution to ensure reliability.
