Thanks for the response. And I apologize if I was in error posting here.
I don't believe my issue is password-related, though. I think the problem is that the system is having trouble detecting/managing devices.
This may not be something that other users can address either. I'm a pretty casual user, though, and figured that any problem I encounter is likely a common one.
All that to say, thank you for your help, and I'll keep searching for solutions.
