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-quickstart skill 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#

bash

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:

bash

VITE_AUTH0_DOMAIN=your-tenant.auth0.com
VITE_AUTH0_CLIENT_ID=your-client-id

3. Configure Auth0 Plugin#

Update src/main.ts:

typescript

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:

vue

<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:

bash

npm run dev

Common Mistakes#

MistakeFixForgot to add redirect URI in Auth0 DashboardAdd your application URL (e.g., http://localhost:3000, https://app.example.com) to Allowed Callback URLs in Auth0 DashboardUsing wrong env var prefixVite requires VITE_ prefix, Vue CLI uses VUE_APP_Not handling loading stateAlways check isLoading before rendering auth-dependent UIStoring tokens in localStorageNever manually store tokens - SDK handles secure storage automaticallyMissing createAuth0 plugin registrationMust call app.use(createAuth0({...})) before mounting appAccessing auth before plugin loadsWrap auth-dependent code in v-if="!isLoading"
