Can you share two-factor authentication?

When 2FA is set up for a personal account, the owner of that account usually receives a 6-digit security token on their phone via SMS, which they’d need to enter in addition to their password to access that account. Shared accounts on the other hand are used by multiple users, not one single individual.

How do you implement two-factor authentication?
