Is My Lovable App Secure?
Lovable apps can be secure if you follow best practices — but they are not secure by default. You need to enable Row Level Security on your Supabase tables, store API keys in the Secrets manager (never in code), and review the built-in security scanner before publishing.
Why this matters
Lovable generates real, deployable code — but AI-generated code can include security gaps like missing RLS policies or hardcoded credentials. Lovable-generated apps use Supabase for their backend, which means security depends on proper Row Level Security (RLS) configuration. Without RLS policies, your database tables may be publicly accessible through the Supabase API — a common misconfiguration that affects many AI-generated apps.
What's at stake
One misconfigured table can expose every user's data. Fixing a breach after launch costs far more than checking security before you publish.
Your checklist.
Row Level Security (RLS) is enabled on all Supabase tables
CriticalLovable uses Supabase for its backend. Every table that stores user data must have RLS enabled with proper policies, or the data is publicly accessible via the API.
Service role key is never used in frontend code
CriticalLovable projects have two Supabase keys: the anon key (safe for frontend) and the service role key (bypasses all security). The service role key must only be used in Edge Functions.
API keys are stored in Lovable Secrets, not hardcoded
CriticalLovable automatically detects API keys pasted in chat and warns you. Always use the Secrets storage and access keys through Edge Functions.
Security View has been reviewed before publishing
ImportantLovable's built-in Security View aggregates findings from its database security advisor and AI-driven code review. Check for Error and Warning severity items before going live.
Authentication flow is properly configured
ImportantIf your app requires login, enable email confirmation and consider the Password HIBP Check in Auth Settings to protect against leaked passwords.
On-demand security review has been run
RecommendedPrompt Lovable with "review my app's security" to trigger a full codebase analysis. This generates a detailed report with specific recommendations.

Frequently asked questions.
Lovable includes a security scanner and warns about hardcoded keys, but it does not automatically configure Row Level Security on your database tables. You need to review and enable RLS policies yourself — this is the most common gap in Lovable apps.
The most common issue is missing Row Level Security (RLS) policies on Supabase tables. When Lovable generates database tables, RLS may not be enabled or configured with proper policies. Without RLS, anyone with your Supabase project URL and anon key can read, modify, or delete data in unprotected tables.
Yes, the Supabase anon key is designed to be public. It operates with limited permissions and respects your RLS policies. The key you must protect is the service role key, which bypasses all security rules.
Open your Lovable project, check the Security View for flagged issues, and prompt Lovable with "review my app's security" for a full codebase analysis. Also manually verify that RLS is enabled on every Supabase table that stores user data.
Yes, but you need to be extra diligent. Enable RLS on all tables, use Edge Functions for any server-side logic, store secrets properly, and consider exporting your code to GitHub for a manual security review before handling sensitive data.
