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.

Why are verification emails not arriving?

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.

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 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.

How do I build an admin dashboard?

Short answer

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.

What an admin dashboard needs

An admin dashboard is really three things working together: a protected route, role checks, and read/write access to tables normal users can't touch.

Roles first. Set up user_roles and an admin role before building the dashboard (see how-do-i-create-different-user-roles).
Route guard. The /admin route should check both "is logged in" and "has admin role", redirecting non-admins away.
Data access. RLS policies on tables like orders or profiles should allow admins to read/update all rows, while regular users only see their own.

Building it

Build an admin dashboard at /admin that's only visible to users with the admin role. It should list all users and let me change their role, and show a table of recent orders.

Ask Lovable this in one go, or iteratively:

Add the role check and route guard.
Add a users table view with role-editing controls.
Add whatever business data (orders, submissions, content) the dashboard needs to manage.

What usually goes wrong

The dashboard UI is hidden from non-admins, but the API/tables it queries aren't restricted, so the data is still fetchable directly.
Giving the dashboard "select *" access to a users table that includes emails or other data you shouldn't expose broadly — scope columns deliberately.
No audit trail: if admins can edit sensitive data, consider asking Lovable to log who changed what and when.

For genuinely complex admin tooling (bulk actions, analytics, multi-role workflows), PromptSites.com can build it properly rather than iterating prompt by prompt.
