For ArcGIS Online apps that have a web site component, like Survey123, StoryMaps, Experience Builder, etc. provide an organization-specific URL. When users reach the app via this URL, then clicking on Sign In would take them to their organization’s custom sign in experience, rather than the generic ArcGIS login dialog.
This would be similar to what is already done for ArcGIS Online. When a user enter's their organization's ArcGIS Online URL they are presented with their organization's custom sign in experience.
The org-specific URLs for the apps would save the user steps in logging in. It would also avoid the all-to-common confusion over entering one's SAML credentials in the generic ArcGIS username/password fields by mistake, and then erroneously requesting a password reset.
For example, if I go to https://umich.maps.arcgis.com, then I get the sign in experience customized for our University of Michigan ArcGIS Online organization, which only shows our SAML login. If I go to https://www.arcgis.com, then I get the generic ArcGIS login dialog with multiple options, and have to go through the extra steps of specifying an organization and clicking through to get to the customized U-M sign in experience.
For the apps, if one goes to https://survey123.arcgis.com, then the sign in workflow is through the generic ArcGIS dialog, and one has to go through those extra steps. I would like to be able to direct our organization’s users to an org-specific URL for Survey123. So that when a user goes to a URL like https://umich.survey123.arcgis.com, and clicks on Sign In, they are taken to our custom U-M sign in experience.
Other apps might follow the same pattern, of putting the org short name in front of their domain, such as https://umich.experience.arcgis.com/, https://umich.storymaps.arcgis.com/, https://umich.dashboards.arcgis.com, etc.
