Twitter now lets users use security keys as the only two-factor authentication method while having all other login methods disabled, as the social network announced three months ago, in March.
2FA is an additional security layer for Twitter accounts requiring users to use a security key or enter a code together with their passwords to log into their accounts.
"Today, we're adding the option to use security keys as your sole 2FA method - meaning you can enroll one or more security keys as the only form of 2FA on your Twitter account without a backup 2FA method," Twitter said.
Twitter has first added security keys as one of several 2FA methods on the web in 2018 and support to use security keys when logging into mobile apps for 2FA-enabled accounts in December 2020.
As mentioned in the beginning, Twitter also added support for using multiple security keys on 2FA-enabled accounts for securely logging in and fending off account takeover attempts following phishing attacks.
To turn on 2FA on your Twitter account, you have to go to your profile menu into Settings and Privacy, then to Security and account access or Account > Security and enable the Two-factor authentication option.
