Use this tool to work through a practical digital-security task at your own pace. It helps you turn what you know into a clear next step, keep track of what matters, and return when you are ready.

What you will do

The exercise takes you one step per page. You can go back to any page you have already seen, change what you entered, and stop whenever you want.

• One identity or several — you choose first, and you can change your mind later.
• Your primary accounts — your main email and your main phone number.
• Secondary contact points — any other emails and phone numbers you use.
• Map your accounts — free form, or guided theme by theme.
• Review, explore and export — as an inventory list and as a constellation map.

Nothing here is a test. There is no score, no grade, and no judgement about how your accounts are arranged. An incomplete inventory is still a useful inventory. You can leave any section empty and come back to it, or leave it out entirely.
