Originally created by @0xcd0e on GitHub (Oct 13, 2021).

Tested von v0.10.1
Steps to reproduce:

  1. Create a new non-reusable authkey
    # headscale preauthkeys -n testns create
  2. Join a new node with it
  3. Try to join another node, which doesnt work (as expected)
  4. Delete the node that was joined in step 2
    # headscale nodes -n testns delete 1
  5. Try to join the second node from step 3 again, it works

This of course requires admin access to headscale in order to completely delete a node, but technically this makes a non-reusable key reusable^^
