What are you talking about? KeepassXC, to my knowledge, is not dependent on any TPM, snd it does support passkeys.
I didn't say a device needs a TPM to support passkeys - I said I believe it it needs one to be a passkey
Thank you for your passive aggressive response caused by poor reading comprehension, though
From what I understand, "passkey" refers to software, so no such thing as "device being a passkey". Unlike a hardware key.
You understand incorrectly. "passkey" refers to a token used for the public key authentication that is used for sign in, which needs to be stored somewhere - this can be stored in a hardware key like a YubiKey, or in your device's credentials manager. In principle, this could be anywhere, but it needs to be somewhere secure to not be trivial to compromise (eg taking out your HDD and just copying your passkey off it)
In Windows' case, this secure credentials store is the TPM chip, which is why you are not able to use passkeys on Windows devices that have no TPM chip (unless you use another hardware implementation).
Tldr: passkeys are data, not software, and to store the data, you need some form of hardware, which needs to be secure to not be a really bad idea.
If you'd like to do some reading before confidently correcting me further, I'd suggest reading about how passkeys work.
That is exactly what I said though - passkeys are software. They're not confined to hardware modules, so there's no such thing as "device being a passkey".
