On October 1st Microsoft Will start disabling Basic Authentication in Exchange Online (unless you've opted to postpone it) so we've designed a tool which creates an excel report of all devices still using basic authentication. The list includes for iPad/iPhone a column saying if the device is on 15.6 or if it should be updated to automatically migrate to modern authentication.
The App will let you know the total number of devices and list the first 10 for free. Nevertheless if you have questions about how to migrate the devices just fire away.
