Hi Michael.<br>So, if I remember coreOS correctly, its the same as all of the cloud based images. It uses SSH keys to authenticate. If you have a an SSH public key in there where you do no longer have the private key for, you can “easily” reset it by 2 ways.<br>1. If its volume based instance, delete the instance but not the volume. Create the instance again by adding your own ssh key into the boot process. This will ADD the ssh key, but not overwrite the existing one in the authorized_key file<br>2. If it is normal ephermal disk based instance, make a snapshot and create a new instance from the snapshot, adding your own ssh key into it.<br><br>Either or, if they are ssh key authenticated (which they should be), there isn’t really an EASY way unless you want to have the volume directly.<br><br>Best regards,<br>//Florian <br><br><blockquote type="cite" style=""> On 16.
