PIN for Additional User???

thank you for the tips @captain11 ... BTW, I have gotten conflicting info regarding whether or not the Master PIN is shared with any Additional Users.  One chat support agent told me that it is NOT. But a phone support agent pointed out that, while it might not be overtly shared, an Additional User has access to the Settings portion of the App, and they would be able to view all the PINs on that App page. Plus, I have been told that the only way an Additional User can have a PIN, for use on the PIN pad or key pad, is by using one of the four (maximum) Custom PINs. Seems like the Additional User option should remain rarely, if ever, used. For practical reasons, the benefit to risk ratio is low. As you wrote, the option for more than four Custom PINs would be best, and very helpful, with minimal security risk. The fact that SS has not added that capability reminds me of the Y2K scenario! 

@dr_dogfish​ I always try to follow KISS (sometimes not successfully). I look at it this way: The master pin and use of the app is the following: my wife and I. Period.  Our two adult kids, when they visit which is not frequently, use the keypad with no issues.  Goes the same way with neighbors, whom I have known for almost 30 years, the FD and the one PIN for contractors that I change when needed. Again, KISS and has worked well since 2012 with our original SS2 system.

@captain11 Apologies, it appears that you may have received incorrect information. The number of available PINs for each SimpliSafe® system has not changed. At this time, each system can support 6 PINs total: 1 Master PIN, 4 Custom PINs, and 1 Duress PIN. 

Of course, if anything changes and the number of available PINs increases, we will be sure to update the Community!
