Im sure most of you use 2FA, the more savy would already be using Authy over google authenticator. I thought of the idea of making a dedicated Authy qube that once setup has no network access, creating a secure, isolated way for me to generate 2FA codes, and act as a backup if ever i lose my phone.

Setup: im using a fedora minimal template

sudo dnf install snapd
sudo ln -s /var/lib/snapd/snap /snap

restart to update pathways

sudo snap install authy

refresh applications & add to shortcuts. launch app. enter password for decryption. shutdown VM. set network VM to none. Done.

i allocated only 600mb ram, & 1CPU, a little slow to boot, but find once running operates fine.

Im sure the even more security minded of you probably rock Yubikeys, and i think the same will be possible using the Desktop Yubico Authenticator which also installs via snap. I havent tried this yet though as all my keys are in authy and im too lazy to change atm.
