Twitter this week announced that it allows users to enroll security keys and use them as the only form of two-factor authentication to secure their accounts.
"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," Twitter explains.
Security keys rely on FIDO and WebAuthn security standards to ensure protection against account compromise attempts, Twitter says.
Twitter first added security keys as a 2FA option in 2018, but only for Twitter.com, and only if another form of 2FA was also enabled.
Starting last year, support for security keys was extended to iOS and Android too, and users were provided earlier this year with the ability to register multiple security keys to their Twitter account.
Now, users can employ those security keys as their sole 2FA method.
