Q: Sierra causing excessive fan operation

After installing Sierra 10.12 the fan on one of my MacBook pro's is running excessively. Activity monitor shows a process "secd" as using 93%of the CPU.  Tried to use the force quit and it comes right back.  On my other MacBook the activity monitor shows the "secd" as 0% CPU and it has no fan issue.

MacBook Pro with Retina display, Mac OS X (10.1.x)
