X (formerly known as Twitter) is set to allow users to login in with a passkey rather than a password, but only on iOS devices.
X earlier announced its intention to roll out passwordless technology, and it has now made the option available to iPhone customers. It enables a faster login process by allowing users to authenticate with whatever they use to lock their device, such as their fingerprint, FaceID, or PIN.
They are also regarded to be safer, because the device generates the underlying cryptographic key, which is unknown to anyone, even the user. This means they are impervious to phishing, which means cybercriminals cannot use fake emails and social engineering strategies to lure them out of targets.
Only for iPhones
The FIDO Alliance designed passkeys and set technological guidelines for them. They employ the WebAuthn standard, which is a vital component of the FIDO2 requirements. The alliance's board of directors includes the majority of top technology firms, including Apple, Google, and Microsoft.
To set up passkeys on X, open the X app on iPhone and go to "Settings and privacy" under "Your account". Then navigate to "Security and account access" and then "Security". Choose "Passkey" under "Additional password protection" and comply with the on-screen directions. You can remove a passkey from the same menu at any moment.
Although X does not make passkeys necessary, it highly encourages users to start using them. Currently, users must have a password-protected account with X before they can set up a passkey, however the company advises customers should "stay tuned" on this.
As iOS devices are the only ones capable of logging into X using a passkey (for the time being), users' passkeys will be synced across their Apple devices via Apple's Keychain password manager, allowing multiple iOS devices to login to X with an identical passkey.
