Twitter frees up use of security key as only 2FA method

Twitter users can already use security keys as the only two-factor authentication (2FA) method to increase the protection of their accounts on the platform. The novelty, which was announced in March, began to take effect from this Wednesday (30), both on mobile devices and on the web version of the service.

According to the social network, physical security keys are the “most efficient way to keep your Twitter account safe “, bringing advantages over other 2FA methods. In SMS or application authentication, for example, it is necessary to send a verification code that can be intercepted by cybercriminals.

With physical keys, which have built-in protection functions, this is more difficult to achieve. According to the company, the devices use FIDO and WebAuthn security standards, being able to differentiate legitimate websites from malicious pages, blocking phishing attempts.

Importantly, the method has been available on the microblogging network since 2018. However, it only worked on browser access and required accounts to have another form of two-factor authentication enabled. Later, the feature arrived in apps for Android and iOS, but it still couldn’t be used as the sole means of protection.

Activation of security keys

Ideal for those who need even greater protection for their Twitter account, the physical security key can be added in the “Account security and access” section of the “Settings” menu of the social network. First, you need to enable the two-step authentication method by SMS or app.

Then open the option “Security Key”, click on “Start” and insert the key into the USB port of the device or synchronize it via Bluetooth or NFC. Then press the button that appears on the switch and follow the on-screen instructions to complete the setup.
