“Passwords are key to protecting everything we do online today, from everything we communicate to all of our finances,” said Knight “But they’re also one of the biggest attack vectors and security vulnerabilities users face today.

That’s why Apple has been pushing so hard for an alternative. Passkeys use Touch ID or Face ID for biometric verification, and iCloud Keychain to sync across iPhone, iPad, Mac, and Apple TV with end-to-end encryption.

Other companies have tried to replace passwords with dedicated hardware, like a physical security key, but that was mostly focused on enterprise users; it also added another layer of complexity. Passkeys have a real shot to take off because they leverage a device you already have.”
