Auth0 Vue.js Integration
Add authentication to Vue.js 3 single-page applications using @auth0/auth0-vue.
Prerequisites
- Vue 3+ application (Vite or Vue CLI)
- Auth0 account and application configured
- If you don't have Auth0 set up yet, use the
auth0-quickstartskill first
When NOT to Use
- Server-side rendered Vue apps - See Auth0 Nuxt.js guide for SSR patterns
- Vue 2 applications - This SDK requires Vue 3+, use legacy @auth0/auth0-spa-js wrapper
- Embedded login - This SDK uses Auth0 Universal Login (redirect-based)
- Backend API authentication - Use express-openid-connect or JWT validation instead
Quick Start Workflow
1. Install SDK
npm install @auth0/auth0-vue
2. Configure Environment
For automated setup with Auth0 CLI, see Setup Guide for complete scripts.
For manual setup:
Create .env file:
VITE_AUTH0_DOMAIN=your-tenant.auth0.com
VITE_AUTH0_CLIENT_ID=your-client-id
3. Configure Auth0 Plugin
Update src/main.ts:
import { createApp } from 'vue';
import { createAuth0 } from '@auth0/auth0-vue';
import App from './App.vue';
const app = createApp(App);
app.use(
createAuth0({
domain: import.meta.env.VITE_AUTH0_DOMAIN,
clientId: import.meta.env.VITE_AUTH0_CLIENT_ID,
authorizationParams: {
redirect_uri: window.location.origin
}
})
);
app.mount('#app');
4. Add Authentication UI
Create a login component:
<script setup lang="ts">
import { useAuth0 } from '@auth0/auth0-vue';
const { loginWithRedirect, logout, isAuthenticated, user, isLoading } = useAuth0();
</script>
<template>
<div>
<div v-if="isLoading">Loading...</div>
<div v-else-if="isAuthenticated">
<img :src="user?.picture" :alt="user?.name" />
<span>Welcome, {{ user?.name }}</span>
<button @click="logout({ logoutParams: { returnTo: window.location.origin }})">
Logout
</button>
</div>
<button v-else @click="loginWithRedirect()">
Login
</button>
</div>
</template>
5. Test Authentication
Start your dev server and test the login flow:
npm run dev

Common Mistakes
| Mistake | Fix |
|---|---|
| Forgot to add redirect URI in Auth0 Dashboard | Add your application URL (e.g., http://localhost:3000, https://app.example.com) to Allowed Callback URLs in Auth0 Dashboard |
| Using wrong env var prefix | Vite requires VITE_ prefix, Vue CLI uses VUE_APP_ |
| Not handling loading state | Always check isLoading before rendering auth-dependent UI |
| Storing tokens in localStorage | Never manually store tokens - SDK handles secure storage automatically |
| Missing createAuth0 plugin registration | Must call app.use(createAuth0({...})) before mounting app |
| Accessing auth before plugin loads | Wrap auth-dependent code in v-if="!isLoading" |
