How do I run a security audit on Lovable?

Open your project's Security view in Lovable to see automated scan results, then ask Lovable in chat to review RLS policies, role storage, and any exposed secrets in detail.

Can users access my database?

Only through the access rules you (or your row-level security policies) allow — Lovable Cloud's database isn't publicly browsable, but a table without RLS enabled is effectively open to anyone with your app's public key.

How do I protect admin pages?

Check the user's role server-side (in the database query or Edge Function) using a dedicated user_roles table — hiding an admin link in the navigation menu doesn't stop someone visiting the URL directly.

How do I protect API keys?

Never put API keys in front-end code — store them as secrets used only inside server functions (Edge Functions), where the browser never sees them.

Where should secrets be stored?

In your project's server-side secrets store, used only inside Edge Functions — never in front-end code, client-side environment variables, or committed to your Git repository.

How do I secure Edge Functions?

Verify the caller's identity and role inside the function itself, validate all input, use secrets rather than hard-coded keys, and don't assume the front end already checked permissions.

How do I prevent database abuse?

Combine row-level security with rate limiting on writes, input validation, and CAPTCHA or similar checks on public forms — RLS stops unauthorised reads/writes, but it doesn't stop a legitimate-looking user from hammering an endpoint.

How do I rate-limit an API?

Add per-user or per-IP request limits inside your Edge Function (or via a Postgres table tracking recent requests), since Lovable doesn't apply rate limiting to your custom endpoints automatically.

Add a CAPTCHA (e.g. Cloudflare Turnstile) to public forms, validate inputs server-side, and rate-limit submissions — client-side-only checks like a hidden field are easy for real bots to bypass.

How do I prevent spam registrations?

Verify email addresses on sign-up, add a CAPTCHA to the registration form, rate-limit sign-up attempts per IP, and check the token server-side before creating an account.

How do I check for exposed environment variables?

Ask Lovable to search your codebase for hard-coded API keys and secrets in front-end files, then move anything sensitive into a server function or edge function.

Is my Supabase anon key safe to expose?

Yes. The Supabase anon key is meant to be public — it identifies your project, it does not grant access on its own. Access is controlled by row-level security (RLS) policies, not by hiding the key.

How do I check a Lovable project for security vulnerabilities?

Open the project's Security view (or the workspace Security center) to run Lovable's built-in scan for exposed secrets, missing RLS, and vulnerable dependencies, then ask Lovable to fix what it flags.

What security checks should I do before launching?

Run Lovable's Security scan, verify RLS on every table, confirm secrets are server-side, check auth flows and admin permissions, and re-test payments before you Publish.

How do I make Lovable perform a security review without changing anything?

Explicitly tell Lovable to run in read-only review mode — ask it to report findings only and not touch any code, then decide what to fix yourself.

Are Lovable websites secure?

Q: How do I secure a Lovable app before launch?

Before launch, verify RLS on every table, move roles into a dedicated user_roles table, confirm no secrets sit in front-end code, and run Lovable's Security view scan.

Q: How do I check Supabase RLS?

Ask Lovable to list every table and its row-level security status and policies in plain language — Lovable Cloud users don't have Supabase dashboard access, so this has to go through chat.

Q: Can users access other users' information?

Only if your row-level security policies are missing or too permissive — with correct RLS, a query for 'my orders' can only ever return rows owned by the logged-in user, regardless of what the front end sends.

Short answer

Lovable includes built-in security scanning and API-key protection, but real security also depends on you setting up row-level security and role checks correctly — it isn't automatic just because you used Lovable.

What Lovable provides by default

Lovable's Security view scans published projects for common issues: exposed secrets in front-end code, missing row-level security (RLS) on Supabase/Lovable Cloud tables, and known dependency vulnerabilities. This runs automatically and flags problems before and after publishing.

What's still your responsibility

Row-level security policies — Lovable can scaffold these, but you need to describe your access rules correctly (who can read/write which rows) for them to be right.
Roles — permissions like "admin" must live in a separate user_roles table, never as a column on a profiles table a user could edit themselves.
Secrets — API keys must be used server-side (Edge Functions), never embedded in the React app.
Business logic checks — a scanner can tell you a table has no RLS policy; it can't tell you your policy logic is wrong for your specific business rules.

How to check yours

Run a security review of this project and check that every table has row-level security enabled, that roles are stored in a separate table, and that no API keys appear in front-end code.

Then open the project's Security view in Lovable to see automated scan results directly.

What usually goes wrong

People treat "Lovable is secure" as a substitute for reviewing their own RLS policies and role logic — the platform reduces common mistakes, it doesn't remove the need to think through who should see what. See /questions/how-do-i-check-supabase-rls and /questions/can-users-access-other-users-information for the specifics. Before a public launch, run through /questions/how-do-i-secure-a-lovable-app-before-launch.
