Hey Sailors,

my Jolla was lying on the table and the sun was shining on the display. There I saw very nice fingerprints from my last unlocking. Then i thougt to myself, that if someone is looking at me several times, while I'm performing the unlocking sequence and then take a look on the display, he might guess my unlock code.

Then I remembered, when I was able to make a guided tour in a well secured datacenter. Our guide had to unlock the doors every time we changed an area of the datacenter. The display of the touchsreen looked like an normal display, but he let us take a look on the screen, an every time he was refreshing the display, the numeric keyboard had a different layout like this:

7 8 9           3 5 7           1 9 6
4 5 6           1 2 4           5 0 3
1 2 3           6 9 0           8 4 2
  0               8               7

I think, this would be a nice optional security feature.
