Who are you?

Shared devices and the wall display are used by several people. So WuselWall asks at the bottom: Who are you? Tap your name (your colour) and your actions are yours — the list shows, for example, who added an item.

• Without a name nothing can be changed. The device tells you: "Tap your name first."
• On the wall display, the device goes back to "nobody" after one minute without a touch, so the next person doesn't act as you by accident.

The guardian PIN

Some things are for guardians only — adding or blocking devices, for instance. On a shared device, tap your name and enter your 6-digit PIN. For the next 15 minutes you can do guardian actions.

• The PIN counts for you only: if someone else taps a different name during that time, they gain no rights.
• A wrong PIN shows how many tries are left. After a few mistakes you have to wait a moment; after ten, the PIN is locked.
• PIN locked or forgotten? Sign in on your own phone and set a new one under Settings → Security → Guardian PIN. That unlocks it at once.

On your personal phone you don't need the PIN: you are already signed in.
