The security system used by Organize is aligned with government guidelines used to classify information. This (or a similar) system is used by most countries, although not all countries have the same number of classification levels. To make the system as universal as possible Organize uses the following classification levels:
For more details on the classification levels have a look at Wikipedia. This article provides a great overview on classified information:
Each task must have a classification level assigned. By default this is "Unclassified". This cannot be changed for the Inbox. For all other Projects, Folders or Meetings you can change the default classification level in the Project Defaults.
"The best secured item is not the one with the biggest lock, but the one you don't know it's there."
Actually the approach is not complicated. It's just a different approach to the "big password lock" on front of every computer. You're not rubbing everybody in the face that you've got something you want to hide, something they are not allowed to see.
The idea is that everybody can take a look if you're on clearance level 0 (Unclassified) and won't see anything that matters. The interesting information is simply not there at all. Change the clearance level and it appears.
You got it! Just set the "Universal Password". This will give you access to all classification levels.
And if you want to automatically protect all items related to a Project, set the Project Defaults to a Security Level above 0.
Organize only provides you with a system to classify your tasks, but not to encrypt or otherwise protect them! You need to make sure for yourself that you comply to the rules associated with the classification levels you use. I.e. in most countries it is strictly forbidden to copy or cary any kind of information classified by the government as Secret or Top Secret on any mobile device at all! If you signed a compliance agreement, please refer to this for more details.
If you store confidential company data using Organize, make sure this is in compliance to any confidentiality and compliance agreements you may have signed.
If you use the classification system for personal data only, it is up to you where you store or copy your data.
The Action Bar contains a Lock Button. Inside the lock you see the number for your current authorization level:
