Remove 2-way verification from QNAP NAS using SSH

If you have forgot, deleted or the authentication-system is not working anymore (like for me), and you do not want to reset your NAS. Connect using Terminal and remove a simple file to disable the 2-way verification.

Connect to NAS using:

"Type ssh admin@xx.xx.xx.xx where xx.xx.xx.xx is the NAS IP." (MAC)

Remove this file (Admin)

[~] # rm /mnt/HDA_ROOT/.config/.qos_config/users/admin/secondSV.conf
