What is a passkey, in practice? Is it a file? A token? Can I keep it in an USB drive? How can I save it in case of device loss? - eviltoast

    Basically dedicated 2FA hardware.

    If you lose it, you’re fucked, end of story.

      You do not need specific hardware to use passkey. For example you can use a password manager like Bitwarden and have your passkeys sync between multiple devices, including a good old regular computer.

      Specific hardware car be use to secure how the passkeys are stored. For example, smartphones usually have a security chip that help s with storing encrypted data.

        Your milage will vary with your corporate policies. You’re not wrong, but you’re not completely right.

        I can’t just pick up any smartphone and install a passkey manager on it. It has to adhere to some specific hardware requirements (like a dedicated chip or instruction set on a CPU).

        So yea, in standing by the 2fa dedicated hardware line. It’s easier than getting into the weeds on hardware device configuration.

          What does this have to do with anything?

          I can’t just pick up any smartphone and install a passkey manager on it.

          Sure, because “any smartphone” includes smartphones that don’t turn on, that are locked with a passcode you don’t know, or that are running a 10 year old OS.

          Which modern smartphones (meaning, still supported by its manufacturer and running a current OS, i.e., iOS 17/18 or Android 14/15) don’t have passkey support? I don’t know of a single one.
