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.
