Design a two-factor authentication product for Gusto.

Gusto, as a platform for critical HR, payroll, and employee management functions, requires robust security. Two-factor authentication (2FA) is essential to mitigate the growing threat of cyberattacks. Passwords alone are insufficient as they can be compromised by bots and other malicious actors. Implementing 2FA ensures that only authorized users can access sensitive company and employee data, thereby increasing user confidence and protecting against unauthorized access.
