This is how I've come to understand it. I welcome any and all corrections.

Passkeys are a cryptographic key stored in a Secure Element. This is usually a private key inside a small cryptographic engine. You feed it some plaintext along with the key ID, and it encrypts it using that key. The outer software then decrypts the ciphertext using the public key. If the decrypted text matches the original plaintext, then that proves you're holding a valid private key, and authentication proceeds.

The private key can be written to and erased from the Secure Element, but never read back out. All it can do is perform operations using the secret key to prove that it is indeed holding the correct secret key.

On phones, the Secure Element is in the hardware of your handset. On PCs, this is most often the TPM (Trusted Platform Module) chip. In both cases, the platform will ask for your PC's/phone's password/fingerprint/whatever before forwarding the request to the Secure Element.

Yubikeys can also serve as a Secure Element for Passkeys; the private key is stored in the Yubikey itself. Further, the Yubikey's stored credentials may be further protected with a PIN, so even if someone steals your Yubikey, they'll still need to know the PIN before it will accept and perform authentication checks. You get eight tries with the PIN; after that, it bricks itself.

The latest series 5 Yubikeys can store up to 100 Passkeys, and Passkeys may be individually deleted when no longer needed. Older series 5 Yubikeys can store only 25 Passkeys, and can only be deleted by erasing all of them.

Theoretically, you can have multiple Passkeys for a given account (one for everyday access; others as emergency backups). Not all sites support creating these, however.

Is there some reason the write-up didn't include a link to the store?

Congratulations, you feckless imbeciles. You've "innovated" general software package management a mere three $(GOD)-damned decades after Redhat and Debian did it.

While you're at it, why don't you "invent" a tiling window manager that can be driven entirely from the keyboard... Oh, wait...

Honestly... Why is anyone still voluntarily giving money to these chowderheads?

I learned a thing today (on Slashdot, no less!). Thank you very kindly.

Perhaps I'm ignorant of the underlying biology involved, but is anyone besides me having difficulty seeing how "antibodies" can be effective against hemotoxins or neurotoxins?

Sixty billion dollars?

Is there any breakdown of this figure? Even if you paid up front for 100,000 headsets, you might only get to $0.1 billion. Where did all the money go? How many prototypes did they make? Were the optics made out of DeBeers diamonds? Did they use AWS or something?

Indeed, when the first SSDs appeared, I cynically observed at the time that the only reason they existed was to make Micros~1's shitty filesystem seem faster than it was. Thus, it was no surprise when Micros~1 started heavily promoting them -- especially those weird "hybrid" drives that bolted an SSD on the side of a traditional hard drive to use as an extended cache.

A diskless 8-bay Synology DS1821+ NAS will set you back USD$999.99

One. Thousand. Dollars. For 4GiB ECC RAM and no storage.

Contrast with the NAS I built seven years ago around an Intel i3, micro-ATX mobo, 32GiB of ECC RAM, six 4GB Hitachi spindles in a RAIDZ2 vdev, and TrueNAS Core (nee FreeNAS). The 8-bay case isn't quite as sexy as Synology's, but it acquits itself quite well.

It cost me USD$1700.00 at the time. By far, the largest expense was the hard drives and RAM, both of which have significantly fallen in price since then. If I were to build the same specs today, it would be at least $400.00 cheaper.

Even so, it was way cheaper than going with Synology. Now it seems Synology have adopted the HP printer ink business model, except without the tissue-thin "loss leader" justification -- no way is that chassis actually worth a thousand bucks.

Build your own NAS. It ain't hard, it will be more capable, and you'll save money.

You'd think after this that people responsible for running real games of chance would design safeguards around the most obvious exploits.

Of course, a liberal would say this.

"Liberals" say lots of true things. Some examples:

• The Earth is approximately 4.5 billion years old.
• The Earth is a spheroid (i.e. not flat).
• Evolution not only exists among all living things, but is also repeatable.
• Homosexuality is not a mental illness.
• White-skinned humans are not inherently superior to humans of any other skin hue.

The above statements are beyond debate. They are true. Any "controversy" you may have heard of is entirely manufactured, and exists solely to waste time and energy, and distract from more pressing matters.

However, there exists a certain mentality that insists that these and many other things cannot possibly be true -- so much so that they've constructed entirely artificial universes for themselves.

They like to call themselves "conservative." But you'll forgive me if I fail to see how willfully separating oneself from objective, observable reality could be described as "conservative."

Stephen Colbert uttered that iconic phrase during the 2006 White House Correspondents' Dinner, as he mocked the sinking approval ratings of America's previous worst President ever, George W. Bush:

Now, I know there are some polls out there saying this man has a 32 percent approval rating. But guys like us, we don't pay attention to the polls. We know that polls are just a collection of statistics that reflect what people are thinking in reality. And reality has a well-known liberal bias.

So, yeah, these guys are going to torture these LLMs by flogging them with trillions of false inputs until they start regurgitating their drivel as if it were fact. And then declare their LLMs are speaking the truth. I mean, think about it. After "investing" billions of dollars developing and training an LLM they're going to put a toll booth in front of, do you really think Microsoft will allow it to recommend Linux-based solutions?

Apparently they're still negotiating the size of the bribe.

News Flash: That slob has no integrity, no ethics, and no compunction against fscking you over once the money lands in his pocket.... excuse me, campaign fund. But don't believe the long-haired hippie freak -- just ask anyone who's done business with him.

What you have to really ask is: for a 10,000 mile trip, [ ... ]

Dude? Seriously? This is your benchmark?

A 10,000 mile trip would take you from New York to Sydney, Australia.

You're correct there aren't a lot of EV chargers between New York and Sydney. However, kindly observe that there also aren't a lot of gas stations in the middle of the Pacific Ocean.

Would it have killed ya to put in a link describing what MPIC is?
