Twitter makes Security Keys the only two-factor authentication method

Twitter added an option last year that allows users to log into its mobile app using a physical security key as a two-factor authentication method. However, you need to enable another authentication method to use it.

Twitter is now improving this feature so that users can add security keys without having to enable another two-factor authentication method for their account.

"The master key may now be the only two-factor authentication option for mobile apps and websites," the tech support account on Twitter said in a tweet.

With this new feature, users can set a physical security key without adding SMS messages or verification codes as a backup.

Twitter mentioned in a blog post that this change is important because not all users can get or want another two-factor authentication method in addition to the passkey, for example

Today we added the ability to use Security Key as the only two-factor authentication method. This means that you can register one or more security keys as the only form of two-factor authentication through your Twitter account. There is no way to backup 2FA.

The platform added: We know this is important for people as not everyone can have a 2FA backup or want to share their phone number with us. We hope that with this update everyone will be able to activate security keys to better protect their Twitter accounts.

Security keys can now be the only two-factor authentication method on mobile and on the web.

A physical security key is a small device that stores authentication codes for apps and websites. This way, no one can log into your account without access to this physical key.

Apple added support for physical security keys in iOS 13.3 that work over the Lightning / USB-C port and even over NFC-compatible devices.

According to Twitter, this new feature is currently rolling out to users of the iOS and Android apps and the platform's website.
