The duration is the amount of time the passcode will remain active for once activated. Each time a Temporary Session Elevation (TSE) passcode is applied to a user session its Duration timer is reset.
NOTE: To prevent a user from reusing the TSE passcode an unlimited number of times configure the “Maximum allowed usages” field when creating the passcode. This provides the option for (0-99999) uses. “0” is used for unlimited.
