After long I tried scryptmail again with my Mac and Safari and additional with my iPhone. It´s still disappointing. On both I´m asked for a second password but I never created one. Scryptmail is only working on my Mac with Firefox. Only there I´m never asked for a second password. Will I have to delete my account. With these restriction it´s useless to me but I still like Scryptmail. Is there any workaround?
