And on occasions it can be hard to come up with a good impression;
for example, after a week or two's rock climbing in the Cuillin of Skye,
the tips of your fingers are worn smooth by the gabbro.
But it does disappoint me that there aren't more options for how
characters are reflected (or not) when typing passwords; not
forgetting passphrases either. LUKS types asterisks under some
circumstances and nothing under others. I haven't managed to pin down
how that decision is made or which binary makes it.
You can make shoulder-surfing more difficult by overwriting each
character a fraction of a second after it's typed.
Cheers,
David.
