We have some Duo users who have multiple associated phones. For example, we define an Administrator user, and associate the phones of all three company sys admins with that user. This allows any one of those sys admins to login to a Duo enabled server, select their phone from the drop-down and login. This ability to assign multiple phones to a user is a wonderful and critical Duo feature for us.
The only problem is that, even when a sys admin picks their phone from the drop-down, it seems to also push to another phone–probably the one that’s first in the list.
Any idea why this is happening and how we can make sure it only pushes to the selected phone?
