Bill.com Multi-Factor Authentication (MFA)/2-step verification

Multi-factor authentication (MFA)/2-step verification is a security process that requires more than one method of authentication from independent credentials to verify your identity.

MFA/2-step verification adds an additional layer of security to your Bill.com account by requiring not only a username and password to log in, but also an additional code sent to your phone. This makes it extremely difficult to break into a Bill.com account.
