The third of the principal officers is the Junior Warden (or Second Warden). The Junior Warden is charged with the supervision of the Lodge while it is “at refreshment” (in recess for meals or other social purposes). In some jurisdictions the Junior Warden has a particular responsibility for ensuring that visiting Masons are in possession of the necessary credentials. In others, this is the job of the Tyler. In some jurisdictions the Junior Warden presides if both the Master and the Senior Warden are absent. In some jurisdictions, the position is an elected office, while in others it is appointed by the Master.

The Wardens are regular officers of the Lodge, meaning that the positions must be filled.
