I do consider the master password to my password manager as my “thing I know”, and not the randomly generated passwords it stores. But you’re saying that have-vs-know is not really important in the security space, that was mostly just a handy shorthand?

so are passkeys just a simplified workflow version of the complicated dance I have to do on windows to get git commits to push easily with the public key from putty-gen? But also the private key is sometimes locked to the device it was generated on? I guess I should read some actual technical docs on em.

I have a basic question, I learned that MFA should draw from multiples of “things you have” (totp) and “things you know” (passwords). There’s all this talk of passkeys replacing passwords, but aren’t passkeys in the “thing you have” category, not the “thing you know” category? My worry is that an unlocked computer or unlocked phone will let someone access ALL of a person’s accounts because now they have the thing and don’t need you at all. Putting access to my entire digital life behind my 4-9 point lock symbol? Or worse, a fingerprint?
