We set up a new patron category with an expiration date of 90 days. We then moved the shared staff accounts over to this new category and set a manual expiration date of a few weeks out. We then went into one of these staff accounts and manually changed the PIN. Now on the patron detail page, it shows their PIN Expires as NEVER. It should show either the manual expiration date we'd already set, or a new date 90 days out.
