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.

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 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.

How do I add user registration?

Q: 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.

Q: 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.

Short answer

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.

What registration involves

Sign-up is part of Lovable Cloud's authentication, alongside login. When a user registers, an entry is created in the auth system; any extra details you want (name, company, plan tier) typically go in a linked profiles table you ask Lovable to create.

Requesting it

Add user registration with email, password and full name. Create a profiles table linked to the user's ID and store their full name there. Require email verification before they can log in.

Be specific about:

Which fields are required at sign-up vs added later.
Whether email verification is required before first login.
What happens immediately after registration (redirect to onboarding, dashboard, etc.).

Where extra profile data lives

Auth systems store the core identity (email, password hash, ID) separately from your own tables. A profiles table, linked by the user's ID, is the normal place for anything else — display name, avatar, preferences. Make sure this table has RLS so users can only edit their own profile.

What usually goes wrong

Storing role or permission data directly on the profile row — keep roles in a separate user_roles table so a user can't edit their own permissions.
Skipping RLS on the new profiles table, meaning any logged-in user can read or edit anyone's profile.
Forgetting to handle the case where sign-up succeeds but profile creation fails, leaving a user with an account but no profile row — ask Lovable to handle this atomically or with a fallback.
Not testing what happens if someone tries to register with an email that already exists.

A quick validation prompt

Test registering two different accounts and confirm each only sees their own profile data, not the other's
