I have 2 yubi keys for the more important systems and store the rest in bitwarden.
With your 2 yubi keys, is it possible to set one up as a clone of the other? I've been manually adding to both keys but that's a pain when I don't have the backup with me.
This one took awhile to wrap my head around as well. I'll try to explain. Each Lemmy instance has its own unique communities. So you might find LOTRmemes on lemmy.one, lemmy.ml, and Lemmy.world. Each is a community of its own and unrelated to the community of the same name on a different instance. You can choose to subscribe to each one you find or only the ones that seem to fit your tastes.
