Twitter announced on Wednesday that it will let people use a security key as their only form of two-factor authentication.

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. We know this is important to people because not everyone is able to have a backup 2FA method or wants to share their phone number with us.
