This plugin adds two-factor authentication (2FA) for SSH sessions to your Volumio device. At this moment there are still some issues when changing the password, as some hard-coded functions require the default password. However, security can be hardened by adding two-factor authentication to (at least) starting SSH sessions.

I’ve already tested it myself, but it will require some more testing. It’s only for the brave (and security conscious)
