British security firm CertiVox has raised $8 million in its second funding round to expand its software-based authentication product. New investor NTT Docomo Ventures and previous investor Octopus Investments backed the said round, according to TechCrunch.

NTT Docomo Senior Vice President Nobuyuki Akimoto said: "CertiVox's M-Pin Strong Authentication Platform is a great and innovative platform, and ideally suited for today's smart devices. M-Pin provides a much-needed advancement for user-friendly, scalable, strong authentication security."

CertiVox will use the new capital for the development of its M-Pin Strong Authentication Platform, a software-based product that can be used as alternative for password-based logins. The platform does not need third-party authentication devices. The company will also expand its sales and marketing campaigns and look for tie-ups with cloud service companies, the report detailed.

The London-based company said over 100 clients are now using its technology. USAF, Parallels, Intel, and Bosch are among its customers. To date, CertiVox has raised a total of $17 million in funding, TechCrunch added.
