I don't do bluetooth. I think I have it, but I'm not even sure
what it is.
Bluetooth (BT) is a low-power, short range wireless protocol. It is often used with
smartphones, keyboards, mice, headsets, and TV remotes (replacing IR).
After the puppy chewed up my BT ear buds, I haven't used it regularly, but some
financial institutions expect me to use a smartphone as a "what you have factor" for
authentication. Previously I had to use a landline and wait in a queue to speak to
an agent, now I can use a web browser and avoid the long wait for the agent "Next".
The new system uses BT to ensure that the phone is close to the PC. If I leave
my phone in another room, it won't allow me to login until I bring the phone closer to
the PC. I'm able to login using Fedora Firefox, so a big step forward over apps
that only work with Windows. My other banks have been "evaluating" two-factor
authentication while reducing call-centre staff and closing branches, so I use of BT
may become the norm.
Laptops usually have some "airplane mode" key combination to disable both wifi
and BT.
