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 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 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 delete a user?

Last checked 31 Aug 2026

Short answer

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.

Why this needs care

Deleting "a user" usually means deleting from two places: the auth system (their login/session record) and your own database rows (profile, posts, orders). Delete only the auth record and you'll leave orphaned rows; delete only the profile row and they can often still log in.

How to do it

Ask Lovable: "Add an admin action to delete a user completely — remove their auth account and cascade-delete their profile, posts and uploads."
Use ON DELETE CASCADE on foreign keys pointing at the user's ID where it makes sense, so related rows clean up automatically when the auth record goes.
For data you must keep for records (e.g. completed orders), anonymise instead of cascading — ask Lovable to null out personal fields rather than delete the row.

When an admin deletes a user, remove their auth account and all owned rows in profiles, posts and comments, but keep their past orders with personal details anonymised.

What usually goes wrong

Deleting the profile row but not the auth account, so the person can still log in to a broken, empty account.
No cascade set up, leaving foreign-key errors or orphaned rows referencing a user that no longer exists.
Self-deletion: letting a user delete their own account without confirmation, or without checking they're not the last admin.
Because Lovable Cloud users don't have direct dashboard access, always route deletions through an admin action Lovable builds, not a manual step you'd expect from a database dashboard.

Letting users delete their own account

If this is a self-service "delete my account" feature rather than an admin tool, say so explicitly when prompting — the confirmation flow and scope of what's deleted should usually differ.
