public application

A public application is an application developers create that does not require users to sign in with an ArcGIS account.

Public applications implement API key authentication or app authentication to authenticate requests to secure resources without prompting users to sign in. Usage costs for accessing secure resources in a public application are billed to the developer's account. Developers with an ArcGIS Online or ArcGIS Enterprise account can choose to omit authentication in public apps if the application only accesses resources with a sharing level set to Everyone (public).
