  2. Clone this repo into the folder of your choice
  3. Run bower install to install Bower components
  4. Clone nodejs-jwt-authentication-sample into a different directory
  5. Serve the API via node server.js; runs on http://localhost:3001
  6. Serve the Polymer project from the project folder: polymer serve (can be accessed in browser at http://localhost:8081, or add the --open flag to auto-launch in your default browser)

What is Auth0?

Auth0 helps you to:

  • Add authentication with multiple authentication sources, 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.
  • Add authentication through more traditional username/password databases.
  • Add support for linking different user accounts with the same user.
  • Support for generating signed Json Web Tokens to call your APIs and flow the user identity securely.
  • Analytics of how, when and where users are logging in.
  • Pull data from other sources and add it to the user profile, through JavaScript rules.
