Add login and signup to protect each user's data

Lovable creates signup, login, and password recovery pages and wires them to the database automatically.

When to use it

You want different people using your app without sharing data or seeing each other's content.

Why it is worth it

Protecting user data and accounts is essential for any app more than one person uses.

Paste this into Lovable's chat in Build mode for your budget tracker project.

Add user accounts to my budget tracking app. Include signup, login, and forgot password pages that match the app's existing minimal style. Require login before viewing the dashboard. Add a Sign in with Google button alongside email and password fields. Show clear error messages for invalid credentials and success confirmations after signup. Each user can only view and manage their own transactions, budgets and spending categories.

Swap budget tracking app for your app type, and transactions and budgets for your data types.

What you get

You have login, signup, and password recovery pages protecting your app, with separate data for each user.
