+### -PasscodeComplexity
+
+> Applicable: Microsoft Teams
+
+Controls whether meeting passcodes should be with the system-default complexity or with lesser complexity of numeric-only digits. If enabled, all meetings organized by these users will have 8-digit simpler numeric-only passcodes.
+
+Possible Values:
+- Default: Alphanumeric with 8 characters (currently default)
+- NumericOnly: 8-digit numeric-only passcodes with lower complexity for all your meetings. Numeric-only passcodes increase the risk of unauthorized access to meetings and don't meet Microsoft's recommended security standards.

 ### -PreferredMeetingProviderForIslandsMode
 Determines the Outlook meeting add-in available to users on Islands mode. By default, this is set to TeamsAndSfb, and the users sees both the Skype for Business and Teams add-ins. Set this to Teams to remove the Skype for Business add-in and only show the Teams add-in.
