I pity the grandpa that has to read all of this and determine if Passkeys are right for them:

> According to Google, you’ll need the following to sign in with a passkey:

> A laptop or desktop that runs Windows 10, macOS Ventura or ChromeOS 109 or later

> A mobile device that runs iOS 16 or Android 9 or later

> A hardware security key that supports the FIDO2 protocol

> Google adds that your computer or mobile device will also need a supported browser, including Chrome 109, Edge 109 or Safari 16 or later.

> [...] Do not create a passkey for a shared device if you don’t want other users to access your account, Google warns.

So much information, so many warnings. I feel nostalgic for passwords just sifting through this stuff.

If you don't understand how an article wasting more words on describing corporate alliances than on how things work, and the latter is needlessly repetitive while also wrong, you are likely to stay on that floor of befuddlement for a long time
