Twitter Strengthens Two-Factor Authentication Options

There are plenty of forms of so-called two-factor authentication when it comes to security, and not all of them are equal. Among the higher tiers of security is an actual, physical hardware key that requires you to plug it in when signing into an account. Fans of the standard will be glad to hear that Twitter has just announced that hardware key-based two-factor authentication can now be used to log in on Android and iOS.

Through Twitter's WebAuthn API, people are able to utilize browser-to-hardware-based authentication, which facilitates additional account security through the use of devices like security keys, mobile phones, and TouchId. 

Account security came into sharp focus for Twitter back in July, when several high profile user accounts were hacked and used to promote a crypto scam.

 

The change affects both the Android and iOS Twitter apps, though it isn't clear if it applies to other first-party apps like Periscope or TweetDeck. Twitter has instructions for how to set things up over on its support site. If you don't have a hardware security key, Yubico is giving folks $10 off their purchase of a single YubiKey hardware 2FA key for the next week with the coupon code TWITTER10. Just make sure you get one with the right connector for your device — that'll probably be USB Type-C for most Android phones.
