There are delete and hide buttons on the right side of the list nodes in the Members section of a ZeroTier network.
Hiding a Member
The member will be de-authorized and hidden from view in the list.
Hidden members can be revealed by setting the “Hidden” checkbox above the member’s list.
Deleting a Member
The member will be de-authorized and completely removed from the list. It’s a little more permanent than hiding.
Recover a Deleted Member
You've deleted a member from your network, possibly by accident, and you want to get it back.
Go to the Settings section of the network
Find the Manually Add Member section
Paste in the Node ID
If you’ve lost Node ID, it can be viewed on the device -in the ZeroTier app.
If you don’t see the Delete and Hide Buttons
You have likely turned off your network’s access control by setting it to Public.
Public networks have no access control. If you deleted or de-authorized a member it would reappear within a few seconds.
See the manual for more info.
Set your network to back to Private.
