On the Linux box I travel with, my main account is not shown on the list of user accounts when you login. There is a dummy account on the list. When I log into that, it has a full complement of apps and data, and the online email account it connects to is a secondary account I use for travel bookings, random notifications and other throwaway purposes. Financial data, important passwords, personal correspondence, etc, are not on that account. Just the usual stuff a non-computer-savvy guy my age would have: browsing, email and Facebook. If they ever comment on it being Linux, I’ll just say “my son set it up for me, I kept having problems with Windows.” But so far, the most they’ve ever done is ask me to show that the laptop can boot up. There’s also full-disk encryption so scans won’t tell them anything worth knowing.

The passwords I use are high-entropy. There’s no duress PIN, though I could set one up if so inclined. So far, I haven’t felt the need to.
