ArcGIS Online unaccountably requesting user logins

We've had behavior with our ArcGIS Online site pop up in the past week that we can't seem to nail down.

ArcGIS Online is suddenly requiring logins for access to web maps and services that have permissions set to 'Public'.  This includes services that are hosted both on our internal servers and in the ArcGIS Online cloud as hosted feature services.  Nothing has changed on our end from a security standpoint.

Anyone else experience the same issue?  Any ideas on how to fix the issue?
