In Part 6 of the Bolt.new Onboarding Series, we turn a static app into a real, user-facing product by implementing authentication and connecting a custom domain. Authentication turns a prototype into a product. It enables real user accounts, persistent data, protected access, and a secure experience people can trust. In this session, you’ll implement email login and Google OAuth, complete the authentication configuration, and set up your custom domain with verified branding, so your app is ready to move from internal build to public launch. *In this video, you'll learn:* - Managing users and authentication settings in Bolt - Customizing confirmation and password reset email templates - Implementing Google Sign-In with OAuth - Setting up OAuth credentials in Google Cloud Console - Purchasing and connecting a custom domain in Bolt - Adding a privacy policy and terms of service - Verifying your branding so your app name appears correctly at sign-in - Resolving the leaked password security warning before publishing By the end of this session, your app will support real user accounts, secure authentication, and verified branding on a custom domain fully prepared for public launch. *Timestamps:* 00:00 - User Management Dashboard Tour 00:45 - Authentication Settings Overview 01:07 - Enable Leaked Password Protection 01:25 - Customize Confirmation Email Templates 02:20 - Build a High-Converting Landing Page 02:55 - Why Add Google Sign-In 03:26 - Google Cloud Console Setup 04:08 - Connect Google OAuth to Bolt 05:07 - Testing Google Sign-In Flow 06:07 - Fix Random Subdomain Branding 06:37 - Buy & Verify a Custom Domain 07:20 - Add Privacy Policy & Terms of Service 08:18 - Google OAuth Branding & Verification 09:21 - Wrap-Up: Verified App Name Display *About Bolt* Bolt turns ideas into production software in minutes, entirely in your browser.
