Twitter users can now use a physical security key to log-in their account

Washington: Twitter had announced a new security key feature in the month of March. On Twitter's official blog, it is stated, "While any form of 2FA is better than no 2FA, physical security keys are the most effective. Security keys offer the strongest protection for your Twitter account because they have built-in protections to ensure that even if a key is used on a phishing site, the information shared can’t be used to access your account." The security keys use the FIDO and WebAuthn security standards to transfer the burden of protecting against phishing attempts from a human to a hardware device. Further, the blog mentions that Security keys can differentiate legitimate sites from malicious ones and block phishing attempts that SMS or verification codes would not.
