Lost private key

Help and Support Help

Hi there
I have lost my private key and can no longer access Volumio via ssh.
I have already tried to edit the file / etc / ssh / sshd_config via USB to set PasswordAuthentication yes ". But unfortunately I cannot find the file on the stick.

Can anyone help me further?

Will SSH be available again after a reset to the factory settings or do I have to install freshly?
