What is the Security Admin Timeout and how does it work?
After you have enabled the Security Admin, going forward you will be prompted to enter your Security Admin PIN (that you specified when you enabled the option).
From the moment you supply the PIN to 'unlock' admin access to the plugin, a countdown timer will begin after which you will be locked-out again.
Any further access to the plugin admin will prompt you to enter your security PIN.
So, the Security Admin Timeout is how long that countdown timer will last.
Note: This does not apply until you enter your PIN again.
To specify the Security Admin Timeout interval, go Shield > Configuration > Security Admin module > Security Admin Settings > Security Admin Timeout and enter how long you want countdown time will last. Default: 30 minutes.
Once the Security Admin session has nearly timed-out, you'll be notified:
This is just a reminder that you'll need to re-enter your security PIN, If you do not do that, Shield will prompt you again to click "OK" or to reload:
You can just click "OK" and Shield will display a new window giving you the opportunity to re-enter your security PIN:
