What is multi-factor authentication (MFA)?

Multi-factor authentication is a security protocol that requires at least two independent credentials to successfully log in. It can be a code sent to your phone, an agreed-upon question you must answer, or even a physical device that provides you with part of the information you need to authenticate you are the appropriate user.

Fundbox customers occasionally encounter MFA when they connect their bank account or their accounting solution to Fundbox.
