Password Protect My Web App
The quickest way to password-protect your web app is to add a simple password gate — a page that requires a shared password before showing the app. For stronger protection, use your hosting platform's built-in password protection (Vercel, Netlify) or add full authentication with individual user accounts.
Why this matters
Password protection is the simplest form of access control. It is perfect for early prototypes, internal tools, or staging environments where you want to keep the public out without building a full login system.
What's at stake
Without any protection, anyone who discovers your URL can access your app. Search engines can index it, bots can crawl it, and competitors can see your work in progress.
Step by step.
Choose your protection level
For quick protection: use your hosting platform's built-in feature (Vercel Password Protection, Netlify Password). For custom control: build a simple password gate page. For full security: implement user authentication.
Use platform-level password protection
Vercel Pro offers Password Protection in project settings — one click to add a shared password. Netlify offers similar features. This protects the entire site without any code changes.
Build a simple password gate (alternative)
Create a landing page that asks for a password. Store the correct password in an environment variable. On correct entry, set a cookie or session flag that allows access to the rest of the app. Keep it simple — this is for basic protection, not security-critical access.
Consider upgrading to full authentication
If you need individual user accounts, password protection is only a stepping stone. Move to Supabase Auth, Clerk, or another provider when you need to know who each user is, not just that they have the password.

Frequently asked questions.
For early prototypes and staging environments, yes. For production apps with user data, no. A shared password can be shared freely — once one person gives it to someone else, you have lost control. Use individual accounts for production.
If deployed to Vercel (common for Lovable exports), use Vercel's Password Protection. For apps hosted on the platform directly, you'll need to build a simple password gate page or implement full authentication.
Yes. If search engines cannot access your pages, they cannot index them. This is usually what you want during development. Remove the protection when you are ready for public traffic.
For platform-level protection: update it in your hosting dashboard. For a custom password gate: change the environment variable and redeploy. For full auth: each user manages their own password through your auth system.
