What is the primary benefit of enabling multi-factor authentication in QuickBooks Online?

Enabling multi-factor authentication (MFA) in QuickBooks Online significantly enhances security by reducing the chance of unauthorized access. MFA adds an extra layer of protection beyond just a username and password; it typically requires users to provide a second piece of information, such as a code sent to their mobile device or an authentication app. This means that even if someone's password is compromised, unauthorized users would still need that second factor to gain access, making it much more difficult for them to breach accounts.

While the ability for multiple user access is a feature of QuickBooks Online, MFA does not inherently influence this aspect, nor does it speed up the login process or specifically provide a backup email for forgotten passwords. Thus, the primary advantage of enabling multi-factor authentication lies in its role in protecting sensitive financial data from potential security threats.
