The various products that GEO Jobe builds to assist clients in managing their ArcGIS organizations are powerful tools that are capable of accessing, editing, copying, and even deleting all of an organization’s content. As such, our products always include checking for a user’s credentials before displaying any information or allowing any actions to be performed.
There are two different methods for authentication when setting up an ArcGIS Organization - OAuth and IWA.
OAuth (currently known as OAuth 2.0) means the users will have a username and password specific to the ArcGIS Organization. They will be prompted to enter those credentials when they try to sign into their org.
(Note: If only SAML is used, that is a type of OAuth)

IWA (also known as Integrated Windows Authentication), is when the credentials are tied in with the account used to sign into a computer. While there may be a “sign in” button, you will NEVER be prompted to enter a username or password.

A simple way to determine if an ArcGIS Organization uses OAuth or IWA is to open up an incognito window in an internet browser, and then navigate to the ArcGIS Organization in question. If being prompted to enter a username and password when signing in, it is using OAuth. Otherwise, the authentication method is IWA.
