X adds support for passkeys globally on iOS

X (formerly Twitter) is rolling out passkey support globally for iOS users, enabling passwordless logins via biometrics, PIN, or security keys and aligning with broader industry adoption by Google, Apple, Microsoft, and others. The move aims to improve account security—especially following the removal of SMS 2FA for non-paying users—and follows a history of high-profile account compromises on the platform; there is no timeline provided for Android support.
