Passkeys will come at a cost
I&#x27;m not a security or crypto guy at all. I found this very difficult to follow, and I suspect others might too.<p>My questions probably seem weird to someone with enough background context to understand the post, but I am getting wrapped around the axle every sentence or two.<p>&gt; <i>It all comes down to one thing - resident keys.</i><p>How&#x2F;why? What&#x27;s the connection to passkeys or HSMs?<p>&gt; <i>we need to understand what a discoverable&#x2F;resident key is</i><p>Yeah okay... does this imply that all resident keys are discoverable keys? Or that all discoverable keys are resident keys? Or both?<p>&gt; <i>You have probably seen that most keys support an &#x27;unlimited&#x27; number of accounts.</i><p>No. Does &quot;keys&quot; here mean passkeys? Or keys stored on HSMs? Or both? Or something else entirely?<p>&gt; <i>This is achieved by sending a &quot;key wrapped key&quot; to the security key.</i><p>Okay so an HSM can apply to an unlimited number of accounts because it can store... some kind of key wrapped in another key (of the same type? different type?)
