So I think I'll need to read up on it a bit. I understand that "Passkeys" try to do something similar as SSH pubkeys.
But do you know a good technical explainer of what's going on and how it works?

(Yes, I could search myself but I am looking for recommendations of articles you have read that you found helpful and clear.)

EDIT: https://passkeys.io did make some things clearer.

@tante Ich habe auf https://karl-voit.at/FIDO2-vs-Passkeys/ zu #Passkeys und #FIDO2 gebloggt und u.a. auch erklärt, weshalb Passkeys in immer mehr Situationen leider nicht mehr gänzlich gegen #Phishing schützen, FIDO2 meiner Meinung nach aber sehr wohl.

D.h. die Hardware-Tokens liefern aktuell den einzig wasserdichten Schutz gegen Phishing. Trotzdem haben Passkeys viele Vorteile gegenüber den üblichen Methoden wie #TOTP, #TAN via #SMS oder #Email, ...

Remember my #issue with same hard- and software but one device doesn't support the native resolution of an external TFT?

I could fix it today with the help of #Claude #AI using its #Opus 4.1 #LLM: https://karl-voit.at/2025/09/14/fix-wrong-34-TFT-resolution/

As so often, it was actually a layer-8-issue. I unintentionally got a Debian testing kernel on the host that worked with the TFT. After using the testing kernel on the other host, the TFT now works on both machines.

However, I now need to find out how to *not* get testing packages for my systems where I don't want it ... different issue.

@alienghic @gnomon thanks for your help! 🙇

Resolved Issue: Lenovo x13 2-in-1 With Wrong 34

Would you help me with an issue? Two almost identical #Lenovo #x13 2-in-1 Gen 5: one is able to use the correct screen resolution of an external TFT, the other one not.

Here's what I did so far: https://karl-voit.at/2025/09/14/fix-wrong-34-TFT-resolution/

The only thing with a difference I found so far is within the output of "lspci -v" which lists different capabilities. But I don't know what to do next ...

I found some time to re-test certain things:

Issue sticks to the SSD when switched between the 2 #X13 devices -> it's a software bug.

Same BIOS settings, same GRUB settings, same BIOS firmware but different "Capabilities" reported by "lspci -v":

Got any further idea I can check?

Here's my article where I summarize the subtle and no so subtle downsides when you choose Markdown for your information instead of a different markup syntax that doesn't come with all the downsides of #MD.
