I have created a a few web apps through ArcGIS Online and although I have shared each with "Everyone (public)", the URL I sent to a colleague brings up the ArcGIS Online sign in page. It seems as if the functionality of sharing apps has changed since the last time I visited our AGOL site. For instance, I no longer see the option to "embed" a map.
Here is an example of the url:
http://uncw.maps.arcgis.com/apps/OnePane/basicviewer/…
Here is the example from a test app created with AppBuilder:
/apps/webappviewer/index.html?…
Does anyone know why I cannot create a valid URL (that does not require a log in) from my shared ArcGIS Online web apps?

I had the same issue a few weeks ago, and I had to change a security setting on ArcGIS Online. Sign into ArcGIS online, then go to "My Organization" link on the top. From there, click on "Edit Settings". On Edit Settings, click on the "Security" tab on the left side column. I checked the second check box down "Allow anonymous access to your organization's website. (Your Organizations Name)." (See screen shot). ESRI also has a link to a support article by the security option:
