How do I add login to Lovable?

Ask Lovable to add authentication — it enables Lovable Cloud (if not already on), then generates sign-up/login pages and wires them to email, Google, or other providers.

How do I add user registration?

Ask Lovable to add sign-up with the fields and verification behaviour you want — it builds the form, creates the user in Lovable Cloud's auth system, and can store extra profile details in your database.

How do I add Google login?

Ask Lovable to add Google sign-in — it can use Lovable's managed Google OAuth for a quick setup, or your own Google Cloud OAuth credentials if you need custom branding or scopes.

How do I add password reset?

Ask Lovable to add a "forgot password" flow — it uses Lovable Cloud's authentication to email a reset link and lets the user set a new password.

Why isn't my login working?

Check the browser console for the actual error first — common causes are unconfirmed email, a redirect URL mismatch, RLS blocking the post-login profile read, or a provider (like Google) misconfigured for the current domain.

Why does my app keep redirecting to login?

This is almost always a session or route-guard bug: either the auth session isn't persisting, or a protected route checks auth state before it's loaded, so it bounces back to login even when signed in.

How do I restrict pages to logged-in users?

Wrap the routes in a protected-route component that checks the current auth session and redirects signed-out users to login, and back this up with row-level security on any data those pages fetch.

How do I create admin users?

Add a `user_roles` table with an `admin` role, assign it to the specific user's ID, and check that role server-side (in RLS policies and any admin-only functions) rather than trusting a front-end flag.

How do I create different user roles?

Store roles in a dedicated `user_roles` table (never a column on the user's profile), and use a security-definer function to check roles inside RLS policies and route guards.

How do I build an admin dashboard?

Ask Lovable to build a role-gated route that lists and manages your data (users, orders, content), backed by RLS policies that only let accounts with the `admin` role query the underlying tables.

How do I prevent normal users accessing admin pages?

Guard the admin route with a check against the user's role from your `user_roles` table (not a front-end-only flag), and mirror that same check in RLS policies on any data the admin page loads.

How do I delete a user?

Ask Lovable to add an admin action that deletes both the user's auth account and their related data (profile rows, uploads, etc.), since removing one without the other leaves orphaned records or broken references.

How do I let users edit their profiles?

Add a profile form bound to a `profiles` table row keyed by the user's ID, with an RLS policy that only lets each user update their own row, not anyone else's.

How do I test authentication properly?

Test with real, separate accounts in a private browser window for each role (signed-out, normal user, admin), checking both the UI and that the underlying API/RLS actually blocks what it should — not just what the interface shows.

Why are verification emails not arriving?

Last checked 31 Aug 2026

Short answer

Usually the email lands in spam, the sending rate limit on Lovable Cloud's default mailer has been hit, or you haven't connected a proper email provider yet.

Common causes

Lovable Cloud's built-in auth sends verification and password-reset emails through a default mail sender that is meant for testing, not production volume. It has strict rate limits and no reputation, so mail providers frequently mark it as spam or block it outright.

Recipient's spam/junk folder — check there first.
Rate limiting: too many sign-ups in a short window on the default sender.
Typos in the email field, or a test address that doesn't actually receive mail.
Auth settings misconfigured (e.g. email confirmation required but sender not set up correctly).

How to fix it properly

For anything beyond testing, connect a real transactional email provider such as Resend and ask Lovable to send auth emails through it.
Ask Lovable: "Connect Resend for authentication emails and use a verified sending domain."
Verify your sending domain's DNS records (SPF/DKIM) with the provider — unverified domains get filtered hard.
Turn off "confirm email" during development if you're just testing flows, then re-enable it before launch.

Connect Resend as the email provider for signup verification and password reset emails, using my verified domain.

What usually goes wrong

Relying on the default sender for a live app — it isn't designed for production traffic.
Forgetting to add the DKIM/SPF DNS records the email provider gives you, so mail from your domain still looks unverified.
Users typing a work email with aggressive spam filtering; ask them to check quarantine, not just spam.

If you're not confident configuring DNS and email providers yourself, PromptSites.com can set up production-ready auth email for you.
