Fingerprint Reader meines Smartphones wird nicht akzeptiert. Neuestes Android und alle Banking Apps gehen damit (Poco F3 mit LineageOS 22). Die EntwicklerInnen haben hier leider entschieden ein umstrittenes Feature von Google zur Überprüfung des genutzten Endgerätes zu verwenden. Sonst alles gut. Danke für die Aufklärung.

Biometric login on GrapheneOS is not supported.

Ich kann mich nicht mehr einloggen, lande immer wieder direkt bei der Eingabe des Passworts. Es gibt keine Fehlermeldung. Vermutlich liegt es aber an GrapheneOS (ohne root). Warum auch immer man ausgerechnet das nachprüfbar sicherste Betriebssystem ausschließt.
