After Tax Fraud Spike, Payroll Firm Greenshades Ditches SSN/DOB Logins

Online payroll management firm Greenshades.com is an object lesson in how not to do authentication. Until very recently, the company allowed corporate payroll administrators to access employee payroll data online using nothing more than an employee’s date of birth and Social Security number.
