Yes, that's true. I try not to forget to take my Yubikey in my pocket when I'm in a public place and have to leave my laptop unattended for a few moments, but I must admit that I tend to leave it connected at all times.
However, I always lock the session.

My nano has touch confirmation. But no biometric.

I've been doing this with a Yubikey Nano (much more practical form factor on a laptop) since Ubuntu 22 😇

Similar to those who tossed away their Bitcoins after having tried it for a few weeks in 2010 ! :)

I had a lot of difficulties with them in the past as well, when working on IPFS projects.

Here is a mistake that most beginners make on Nostr, in my experience, and one that most clients are not very helpful with:

1. Someone generates a new keypair.
2. The client they use for their onboarding process then suggests a few relays, which they accept.
3. They then write a bio, which is published on those relays.
4. Later, after a few weeks of using Nostr, they choose other relays, sometimes keeping only one or two of the original relays.
5. Since they don't really care about their bio, they don't republish it on the new relays.

As a result, their profile is difficult for clients to access, and other users do not know "who is speaking" when they see their notes, until someone explains it to them.

So, to avoid this, clients should simply republish the kind 0 on the new relays immediately when a new kind 10002 is published.

Don't lose faith. Nostr not having an echo chamber algorithm means you see a lot more of the ideas spectrum than on legacy social media. Nazis / morons just have a bigger mouth than civilized people. Don't let that discourage you.

You can eat and receive medical care. What more could you ask for ! :)
