Does anyone know that changing the app authentication delegation will require users to set up a new app password?

This caught us by surprise when we were instructed to do so by Blackberry support when troubleshooting an issue.

Yes, we have run into that as well. Currently We are using Access as the AuthDelegate, because some of the functionality it provides. (Microsoft Web Apps, Blackberry App store without using UEM client.) We have also seen some funky provisioning if we have more than one authdelegate set. Plus there is the issue of remembering the different password for each app if they are not the same. Plus expiration times. We did away with multiple authdelegates.
