# Auth0 React Token Renewal
2+
3+
This sample demonstrates how to silently renew `access_token`s in a React application with Auth0. The sample uses the create-react-app.
4+
5+
## Getting Started
6+
7+
Create a new API in the [APIs section](https://manage.auth0.com/#/apis) and provide an identifier for it.
8+
9+
Clone the repo or download it from the React quickstart page in Auth0's documentation. Install create-react-app and the dependencies for the app.
10+
11+
```bash
12+
npm install -g create-react-app
13+
cd 05-Token-Renewal
14+
npm install
15+
```
16+
17+
## Set the Client ID, Domain, and API URL
18+
19+
If you download the sample from the quickstart page, it will come pre-populated with the **client ID** and **domain** for your application. If you clone the repo directly from Github, rename the `auth0-variables.js.example` file to `auth0-variables.js` and provide the **client ID** and **domain** there. This file is located in `src/Auth/`.
20+
21+
You should also provide the identifier for the API you create in the Auth0 dashboard as your `apiUrl`.
22+
23+
## Set Up the `silent.html` File
24+
25+
If you download the sample from the quickstart page, it will come pre-populated with the **client ID** and **domain** for your application. If you clone the repo directly from Github, edit `silent.html` and add your **client ID** and **domain**.
26+
27+
## Run the Application
28+
29+
The development server that comes with create-react-app can be used to serve the application.
30+
31+
```bash
32+
npm start
33+
```
34+
35+
The application will be served at `http://localhost:3000`.
36+
37+
## Making It Live
38+
39+
To make the silent authentication work on a live environment, you'll need to edit the two `localhost` urls in `silent.html` and the one `localhost` url you have in the `auth0-variables.ts` file.
40+
41+
## Troubleshooting
42+
If you see an error on renewal saying `login_required`, that means you may be using the Auth0 dev keys for whichever social login you're testing. You'll need to add your own keys for this to work.
43+
44+
## What is Auth0?
45+
46+
Auth0 helps you to:
47+
48+
* Add authentication with [multiple authentication sources](https://docs.auth0.com/identityproviders), either social like **Google, Facebook, Microsoft Account, LinkedIn, GitHub, Twitter, Box, Salesforce, amont others**, or enterprise identity systems like **Windows Azure AD, Google Apps, Active Directory, ADFS or any SAML Identity Provider**.
49+
* Add authentication through more traditional **[username/password databases](https://docs.auth0.com/mysql-connection-tutorial)**.
50+
* Add support for **[linking different user accounts](https://docs.auth0.com/link-accounts)** with the same user.
51+
* Support for generating signed [Json Web Tokens](https://docs.auth0.com/jwt) to call your APIs and **flow the user identity** securely.
52+
* Analytics of how, when and where users are logging in.
53+
* Pull data from other sources and add it to the user profile, through [JavaScript rules](https://docs.auth0.com/rules).
54+
55+
## Create a free Auth0 account
56+
57+
1. Go to [Auth0](https://auth0.com/signup) and click Sign Up.
58+
2. Use Google, GitHub or Microsoft Account to login.
59+
60+
