Twitter now lets users secure accounts with just a security key.
The social networking site has revealed people can take up the option to use a physical security key as their sole form of two-factor authentication.
In a blog post, the company said: "Starting today, people on Twitter have the option to use security keys as their only form of two-factor authentication (2FA), which is the most effective way to keep your Twitter account secure.
"While any form of 2FA is better than no 2FA, physical security keys are the most effective. Security keys are small devices that act like keys to your house.
"Just as you need a physical key to unlock the door to your home, you need a security key to unlock access to your account."
Twitter added: "They use the FIDO and WebAuthn security standards to transfer the burden of protecting against phishing attempts from a human to a hardware device.
"Security keys can differentiate legitimate sites from malicious ones and block phishing attempts that SMS or verification codes would not."
