Keyfile? YubiKey? Both?
I, myself, use just use a standard keyfile that I generated with KeePass. This should be plenty secure along with a strong password.
Some guy once showed me a neat trick. Instead of generating the keyfile in KeePass, he would instead generate a very long password, paste it into a txt file, and use that as a keyfile. That way, it is much easier to backup, since it is just a single-line string of text. It can even be backed up as a QR code very easily.
Don't get me wrong, I prefer if platforms don't take a political stance at all. That's the reason why I use platforms like Lemmy.
I am simply just pointing out that conservative ideologies have been oppressed online and in the media for the greater part of a decade. Funny to see how the left are losing their minds now that they get a little taste of it themselves.
