X, aka Twitter, is expanding support for passkeys-an entirely new, much more secure login method compared with those old-school passwords-to all iOS users around the globe. The feature launched in January, but only to iOS users in the U.S.

The technology firm updated the X @Safety account on Monday, stating that passkeys can be used worldwide by iOS users for logging in. The same technology is already embedded in popular apps and services such as PayPal, TikTok, WhatsApp, GitHub, and many others. Passkeys have been the default sign-in option for all Google users since last fall. Moreover, Apple, Microsoft, Amazon, and many other firms support it.

Passkey technology has been developed by Google, Apple, Microsoft, and the FIDO Alliance in partnership with the World Wide Web Consortium. The idea is to bring across passwordless logins across diverse devices, operating systems, and web browsers. Unlike the classic login modes that call for a username-password combination to verify entry, passkeys use Face ID or Touch ID or even a PIN or a physical security authentication key to authenticate access. It's blending together the best of two-factor authentication into one step-so logins are smoother while security is higher.

For X, it could potentially prevent hackers from infiltrating users' accounts. The social network has been hacked more often than most people can shake a virtual stick at-throughout its existence, including a hacking in January in which the U.S. Securities and Exchange's X account posted an unauthorized update on Bitcoin ETF approval. Probably the most infamous one was the hacking of Donald Trump Jr.'s son's X account where it put a fake message saying he died. Still another crypto scam from 2020 compromised most of the bigger accounts including even Apple, President Biden, and X owner Elon Musk amongst others.

The addition would also help out X users who now rely on SMS 2FA to re-secure their accounts following an announcement last year that option would be removed for non-paying users. X had argued that the cost-cutting measure could be abused by bad actors, such as in the case of SIM swaps. The reality was that it made X less secure.

X is giving its users the "how-to" in getting started with passkeys on iOS. But it isn't saying yet when the choice will come to Android.
