If I do not close my app completely (so I do it only in the background), then I can start 1P (also days later) again only with the PIN code. I like this very much because my masterpassword is very long. ;-)
But - for security reason - is it possilbe that 1P accept only once the PIN code? If I (or somebody else) insert the wrong PIN the first time, then 1P should immediately close completely and ask for the masterpassword again. So 1P should not allow to insert the PIN again and again.
In this case I would prefere to login by PIN also, if 1P was closed completely.
