Apple's latest preview version of Safari features support for the WebAuthentication (WebAuthn) API that lets users login using USB security sticks, according to the release notes. Users can enable a feature that allows them to log in using USB-based CTAP2 sticks, which offer a higher level of protection than regular text-based passwords. The hardware devices are typically used in conjunction with passwords, a one-two protection punch that makes hacking and phishing exponentially more difficult.
