The tutorials now support <\/span>two authentication options<\/span>: <\/span>API key authentication<\/span><\/b> and <\/span>user authentication<\/span><\/b>. This update gives you the flexibility to choose the authentication method that best suits your application and security needs.\u00a0<\/span>\u00a0<\/span><\/p>\n In this blog post, we\u2019ll walk you through the details of both options and what they mean for your development experience.<\/span>\u00a0<\/span><\/p>\n"},{"acf_fc_layout":"content","content":" The first <\/span>option<\/span> is <\/span><\/span>API key authentication<\/span>.<\/span><\/span><\/a> In<\/span> the tutorial, you <\/span>us<\/span>e <\/span>an API key to authenticate requests to ArcGIS <\/span>content, services, and resources<\/span>. <\/span>The<\/span> demo app<\/span> at the top of the <\/span>tutorial<\/span> opens directly in your browser and is ready for you to interact with. You can also view and <\/span>modify<\/span> the demo app\u2019s code in <\/span>CodePen<\/span>.\u00a0<\/span><\/span>\u00a0<\/span><\/p>\n This option is ideal if you’re new to ArcGIS and location services.

The app will access ArcGIS content, services, and resources on their behalf. When you click <\/span>Start demo <\/span><\/b>on the demo app at the top of the tutorial, you will be prompted to sign in with your ArcGIS account credentials.
