DNA testing and genealogy companies are stepping up user account security by mandating the use of two-factor authentication, following the theft of millions of user records from DNA genetic testing giant 23andMe.

Ancestry, MyHeritage, and 23andMe have begun notifying customers that their accounts will use two-factor (2FA) by default, a security feature where users are asked to enter an additional verification code sent to a device they own to confirm that the person logging in is the true account holder.
