+    \begin{itemize}
+        \item unsichere Passwörter wie "test", "test123"
+        \vfill
+        \item<2-> viele Accounts mit gleichem Passwort
+        \vfill
+        \item<3-> sichere Passwörter wie "eiCmX\`HvW?\#o3\$Yktk2rkosHu-DW=2"

+\begin{frame}{Lösung: Diceware}
+    \begin{itemize}
+        \item benötigt einen D6-Würfel, ein Stück Papier, einen Stift und Zeit
+        \vfill
+        \item Liste mit Worten von diceware.com herunterladen
+        \vfill
+        \item jedes Wort wird mit 5 gewürfelten Ziffern identifiziert
+        \vfill
+        \item 7 gewürfelte Wörter haben eine Entropie von ca. 90 Bits
+        \vfill
+        \item leicht zu merken

+\begin{frame}{Zahlen}
+    \begin{itemize}
+        \item es gibt \(6^5=7776\) viele mögliche Kombinationen pro Wort
+        \vfill
+        \item bei 7 Wörtern sind das also \(7776^7=17190708 \cdot 10^{20}\) mögliche Kombinationen
