No other form of two-factor authentication needed

Keeping your Twitter account secure is about to get a whole lot easier as the social network has announced that users now have the option to use a security key as their only form of two-factor authentication (2FA).

While any form of 2FA can help further secure your online accounts, physical security keys are the most effective way to do so. This is because security keys offer built-in protections to ensure that even if they are used on a phishing site, the information stored on them can't be used to access your accounts.

At the same time, security keys also transfer the burden of protecting against phishing attempts from a human to a hardware device. They can even differentiate between legitimate sites and malicious ones while blocking phishing attempts that SMS verification codes would be unable to.

Committed to security

Twitter has been a vocal proponent of using some form of 2FA to secure one's online accounts for some time now. For instance, back in 2018 the social network added the option to use security keys as one of several 2FA options though this initial support only worked on the company's website and not its mobile app while requiring accounts to also have another form of 2FA enabled.

The following year Twitter upgraded its security key support to use the latest WebAuthn standard and enabled the ability to use 2FA without requiring a phone number. This was an important upgrade as it allowed users to protect their accounts from SIM-swapping attacks.

Last year the company added security key support on both iOS and Android in addition to on the web and this year it added the ability to register multiple security keys to a Twitter account so that users could have backups in case of emergencies.

Now though, Twitter users will be able to use security keys as their sole 2FA method without requiring a backup method.
