Question 1

Are Lovable websites secure?

Accepted 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.

Question 2

How do I run a security audit on Lovable?

Accepted Answer

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.

Question 3

How do I secure a Lovable app before launch?

Accepted Answer

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.

Question 4

How do I check Supabase RLS?

Accepted Answer

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.

Question 5

Can users access my database?

Accepted Answer

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.

Question 6

Can users access other users' information?

Accepted Answer

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.

Question 7

How do I protect admin pages?

Accepted Answer

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.

Question 8

How do I protect API keys?

Accepted Answer

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.

Question 9

Where should secrets be stored?

Accepted Answer

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.

Question 10

How do I secure Edge Functions?

Accepted Answer

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.

Question 11

How do I prevent database abuse?

Accepted Answer

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.

Question 12

How do I rate-limit an API?

Accepted Answer

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.

Question 13

How do I stop bots?

Accepted Answer

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.

Question 14

How do I prevent spam registrations?

Accepted Answer

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.

Question 15

How do I check for exposed environment variables?

Accepted Answer

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.

Question 16

Is my Supabase anon key safe to expose?

Accepted Answer

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.

Question 17

How do I check a Lovable project for security vulnerabilities?

Accepted Answer

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.

Question 18

What security checks should I do before launching?

Accepted Answer

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.

Question 19

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

Accepted Answer

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.
