Yes, this is true, however, that means an external actor is able to execute arbitrary code in your origin, so they could also trick the user into signing malicious payloads with ev…

Hmm, can you provide further details? I'm using it on Android in Chrome and Brave, and it works fine.

That would either mean you have arbitrary, malicious code executing in the bound origin (the origin was hacked and shipped malicious code), or you allowed random callers externally…

You can run the PassSeed code/mechanism on your own domain or localhost to ensure it's not subject to malicious host exfiltratuon. I agree that one should only trust a foreign host…

A roaming authenticator does not have access to a CTAP mechanism to query the platform’s credential store. CTAP defines how the platform queries a roaming authenticator, in that di…

There's also the specific case of synced passkeys, which aren't exposed to CTAP management APIs for external parties, only to the OS/platform itself. You seem tied to a narrative w…

It's not just about the WebAuthn API, you're talking about passkeys as if their key bundles are freely accessible to random userland actors, which is absurd. If that were the case,…

The underlying CTAP implementations are only used by the platform to facilitate core activities, they are not used to expose key pairs to external parties. Please link to where any…

No need for the "oh dear"-ing before you provide evidence. I'm not aware of any command for fetch or enumeration of public keys in CTAP (was rather confident it doesn't provide any…

It's a deliberate architectural decision that passkey authenticators not allow any retrieval or enumeration of key pairs - they don't even have internal APIs for it. This holds tru…

The interesting thing about Passkeys is that they are only ever output in the client create() call, and the platform does not retain them for disclosure after that, so if you don't…

Saw your post above - I didn't "assert falsehoods", both are missing major browser support: https://caniuse.com/mdn-api_credentialscontainer_get_publick... https://caniuse.com/mdn-…

I addressed this in the post - neither is available across all major browsers: https://backalleycoder.com/posts/passseeds-an-experiment-in-... Ironically, you could make a pollyfil…

How it's better: automatically synced across all a user's devices, not subject to manual interactions with input fields (you can't programmatically request/regen passwords the same…

Just sounded cooler , and I was on the team that worked on Passkeys at Microsoft, so I wanted to poke them a bit (in a friendly way).

Passkeys can be hijacked to serve as cryptographic seed material that is securely synced across all of a user’s devices, enabling the generation of a wide range of cryptographic ke…

Also take a look at DIF's Identity Hub - a large-scale initiative that goes far beyond a social server/mailbox, and incorporates solutions for the identity issues people here have …

This is unrelated to any previous demo/work Accenture has shown. (I work on this @ MSFT)

Other way around: the sat system supports Bitcoin, not BCash.

Correct - you can increase the units in circulation without destroying the purchasing power of those who currently hold the asset, which is a huge advantage over traditional fiat c…

Property is subject to bubbles, and in almost any economic recession prices of real estate tend to fall (demand drops, and sellers/supply grows). Bitcoin is a far better asset hedg…
