Re: Only a limited ban then
Yes, as long as they are able to use their phone in that location. For secure sites, personal devices are usually not allowed to enter the facility, so you wouldn't be able to access it. For other sites, they don't care about use in the building, but use on a device with their data on it. So this really only affects people who actually bring their own mobile device for government work. I can't believe people do that very often. I don't like installing any employer-provided software on my devices. I'm willing to accept SMS messages and calls to my mobile number and to use multifactor authentication apps which are not tied to a profile. If they want more than that, they buy the device to run the code on and they can control it as tightly as they like. For the same reason, I won't use my personal laptop for work and they won't install anything on it. So far, my employers have accepted that preference.
