I've made a first translation file for german: GitHub
All strings are translatable, but
line 98 ist not working:
'notes' => sprintf(__("For example Font Awesome checkmark icon e.g. %s\n(You need to include Font Awesome on your own)"), "<i class='fa fa-check'></i>"),
with single quotes it works, but without the newline \n.
Maybe don't use the \n? Or delete part of string "(You need to include Font Awesome on your own)", because Font Awesome is already included in PW.
same problem with line 217:
'notes' => __("Default true\nIt has been suggested that this setting can effectively help to reduce identity theft through XSS attacks"),
