New user, suggestion changes (trivial tweaks and expanded passcode options)

New user to 2fas user, loving it so far. Noticed some small things and figured it may help posting it here for consideration.

[ ] Introduction paragraph text formatting issue
[ ] Denied camera presentation on import screen
[ ] QR code scan page may be better with scroll hint

The application's pin security option provides only a 4-pin or 6-pin numerical entry:

It would be cool to have additional options for extended pins, like iOS's existing passcode configurations:
