You built your app with AI.
Now add real auth.
Vibe coding tools like Cursor, Bolt, Lovable, Replit, and v0 are incredible for building apps fast. But when it's time to add authentication, AI-generated auth code is a security risk. VibeLogin gives you production-ready login, signup, sessions, and OAuth without writing any auth code yourself.
The problem with AI-generated auth
When you ask an AI coding tool to “add login to my app,” it generates auth code that looks correct but is often insecure:
- Passwords stored with weak hashing or in plain text
- Sessions stored in localStorage (vulnerable to XSS)
- No CSRF protection on login forms
- JWT tokens that never expire or rotate
- No rate limiting on login attempts
- No email verification or password reset flow
You shouldn't have to audit AI-generated security code. VibeLogin handles all of it so you can focus on your product.
How VibeLogin works with your AI-built app
Add the MCP server to your IDE
Connect VibeLogin to Cursor, Claude Code, or Windsurf. One-time setup.
Say "add auth"
The MCP server creates your project, enables login methods, and scaffolds all the files automatically.
Ship
Your app now has login, signup, password reset, magic links, email OTP, OAuth, sessions, and email verification. All production-ready.
Or install the SDK manually — npm install @vibelogin/nextjs, add 3 files, 5 minutes. Read the quickstart →
Works with every AI coding tool
VibeLogin works with any app that uses Next.js — regardless of which AI tool built it. It also has a REST API that works with any framework.
