Add Login to Your Nuxt.js Application

This Quickstart is currently in Beta. We’d love to hear your feedback!

Use AI to integrate Auth0

If you use an AI coding assistant like Claude Code, Cursor, or GitHub Copilot, you can add Auth0 authentication automatically in minutes using agent skills.Install:

npx skills add https://github.com/auth0/agent-skills --skill auth0-nuxt

Then ask your AI assistant:

Add Auth0 authentication to my Nuxt app

Your AI assistant will automatically create your Auth0 application, fetch credentials, install @auth0/auth0-nuxt, configure the module, and set up your routes. Full agent skills documentation →

Prerequisites: Before you begin, ensure you have the following installed:

Node.js 20 LTS or newer
npm 10+ or yarn 1.22+ or pnpm 8+
jq - Required for Auth0 CLI setup

Nuxt Version Compatibility: This quickstart works with Nuxt 3.x out of the box. For Nuxt 4.x, ensure you’re using Nuxt 4.2+.

Get Started

This quickstart demonstrates how to add Auth0 authentication to a Nuxt.js application. You’ll build a secure single-page app with login, logout, and user profile features using the Auth0 Nuxt SDK.

Create a new project

Create a new Nuxt project for this Quickstart

npx nuxi@latest init auth0-nuxt-app

Open the project

cd auth0-nuxt-app

Install the Auth0 Nuxt SDK

npm add @auth0/auth0-nuxt && npm install

Setup your Auth0 App

Next up, you need to create a new app on your Auth0 tenant and add the environment variables to your project.You can choose to do this automatically by running a CLI command or do it manually via the Dashboard:

CLI
Dashboard

Run the following shell command on your project’s root directory to create an Auth0 app and generate a .env file:

AUTH0_APP_NAME="My Nuxt App" && brew tap auth0/auth0-cli && brew install auth0 && auth0 login --no-input && auth0 apps create -n "${AUTH0_APP_NAME}" -t regular -c http://localhost:3000/auth/callback -l http://localhost:3000 -o http://localhost:3000 --reveal-secrets --json > auth0-app-details.json && CLIENT_ID=$(jq -r '.client_id' auth0-app-details.json) && CLIENT_SECRET=$(jq -r '.client_secret' auth0-app-details.json) && DOMAIN=$(auth0 tenants list --json | jq -r '.[] | select(.active == true) | .name') && echo "NUXT_AUTH0_DOMAIN=${DOMAIN}" > .env && echo "NUXT_AUTH0_CLIENT_ID=${CLIENT_ID}" >> .env && echo "NUXT_AUTH0_CLIENT_SECRET=${CLIENT_SECRET}" >> .env && echo "NUXT_AUTH0_SESSION_SECRET=$(openssl rand -hex 64)" >> .env && echo "NUXT_AUTH0_APP_BASE_URL=http://localhost:3000" >> .env && rm auth0-app-details.json && echo ".env file created with your Auth0 details:" && cat .env

$AppName = "My Nuxt App"; winget install Auth0.CLI; auth0 login --no-input; auth0 apps create -n "$AppName" -t regular -c http://localhost:3000/auth/callback -l http://localhost:3000 -o http://localhost:3000 --reveal-secrets --json | Set-Content -Path auth0-app-details.json; $ClientId = (Get-Content -Raw auth0-app-details.json | ConvertFrom-Json).client_id; $ClientSecret = (Get-Content -Raw auth0-app-details.json | ConvertFrom-Json).client_secret; $Domain = (auth0 tenants list --json | ConvertFrom-Json | Where-Object { $_.active -eq $true }).name; Set-Content -Path .env -Value "NUXT_AUTH0_DOMAIN=$Domain"; Add-Content -Path .env -Value "NUXT_AUTH0_CLIENT_ID=$ClientId"; Add-Content -Path .env -Value "NUXT_AUTH0_CLIENT_SECRET=$ClientSecret"; $SessionSecret = -join ((1..128) | ForEach {'{0:X}' -f (Get-Random -Max 16)}); Add-Content -Path .env -Value "NUXT_AUTH0_SESSION_SECRET=$SessionSecret"; Add-Content -Path .env -Value "NUXT_AUTH0_APP_BASE_URL=http://localhost:3000"; Remove-Item auth0-app-details.json; Write-Output ".env file created with your Auth0 details:"; Get-Content .env

Before you start, create a .env file on your project’s root directory

.env

NUXT_AUTH0_DOMAIN=YOUR_AUTH0_APP_DOMAIN
NUXT_AUTH0_CLIENT_ID=YOUR_AUTH0_APP_CLIENT_ID
NUXT_AUTH0_CLIENT_SECRET=YOUR_AUTH0_APP_CLIENT_SECRET
NUXT_AUTH0_SESSION_SECRET=YOUR_SESSION_SECRET
NUXT_AUTH0_APP_BASE_URL=http://localhost:3000

Head to the Auth0 Dashboard
Click on Applications > Applications > Create Application
In the popup, enter a name for your app, select Regular Web Application as the app type and click Create
Switch to the Settings tab on the Application Details page
Replace the values in the .env file with the Domain, Client ID, and Client Secret values from the dashboard
Generate a session secret by running: openssl rand -hex 64 and use it for NUXT_AUTH0_SESSION_SECRET

Finally, on the Settings tab of your Application Details page, configure the following URLs:Allowed Callback URLs:

http://localhost:3000/auth/callback

Allowed Logout URLs:

http://localhost:3000

Allowed Web Origins:

http://localhost:3000

Allowed Callback URLs are a critical security measure to ensure users are safely returned to your application after authentication. Without a matching URL, the login process will fail, and users will be blocked by an Auth0 error page instead of accessing your app.

Allowed Logout URLs are essential for providing a seamless user experience upon signing out. Without a matching URL, users will not be redirected back to your application after logout and will instead be left on a generic Auth0 page.Allowed Web Origins is critical for silent authentication. Without it, users will be logged out when they refresh the page or return to your app later.

Configure the Auth0 Nuxt module

nuxt.config.ts

export default defineNuxtConfig({
  devtools: { enabled: true },
  modules: ['@auth0/auth0-nuxt'],
  runtimeConfig: {
    auth0: {
      domain: process.env.NUXT_AUTH0_DOMAIN,
      clientId: process.env.NUXT_AUTH0_CLIENT_ID,
      clientSecret: process.env.NUXT_AUTH0_CLIENT_SECRET,
      sessionSecret: process.env.NUXT_AUTH0_SESSION_SECRET,
      appBaseUrl: process.env.NUXT_AUTH0_APP_BASE_URL,
    },
  },
})

Create Login, Logout and Profile Components

Create files

mkdir -p app/components && touch app/components/LoginButton.vue && touch app/components/LogoutButton.vue && touch app/components/UserProfile.vue

And add the following code snippets

<template>

    href="/auth/login"
