alt Hacker News> There is nothing to prevent you from entering your super secure u quiet password on the wrong site if you get phished.
You replied to someone talking about password managers, which objectively do exactly that.
> Unique strong passwords, TOTP, 2FA, one time sign in emails, none of those offer this stuff.
And Passkeys don't offer portability, user choice, or user control.
Cryptography may be a solution, passkeys are one technical implementation that at is core is designed around smartphone-first, vendor-first, brand-loyality-first thinking.

password managers do not do that. open up your password manager, press "copy" on the password, and then paste it into a random website. it will paste it.
(i think 1password just recently enabled an option that will warn you if the website is different than the one it has, but it still lets you paste it)

This is objectively false. Every major platform provides user choice in Passkey Manager. It's the same flow/settings to setting up a third party Password Manager.
All of the ecosystems have defaults that include some amount of portability: iOS defaults to Passkeys synced through iCloud Password Manager and backed up/restored with device backups. Android defaults to Passkeys synced through Chrome Password Manager. Windows defaults to Passkeys synced through Edge Password Manager. All of the ecosystems have plugin systems to support third party Password/Passkey Managers such as 1Password or Bitwarden.
Most devices that support Passkeys support a QR code bootstrapped flow for cross-device/cross-ecosystem Passkey challenge signing via Bluetooth LE.
Most ecosystems deliberately don't provide explicit private import/export to help protect users, but that's more an implementation detail than a technical requirement, and mostly not an implementation detail for "lock in" reasons but for simple security reasons: the private key you cannot export is the private key that is harder to steal by bad actors. The private key that you cannot manually import is the private key that can't be installed by bad actors.
