A better way to increase web security.
Online security experts will tell you that user passwords offer almost no protection at all. They are just too easy to crack or steal. That's why companies and organizations are increasingly adopting mobile two-factor authentication to strengthen passwords and safeguard online information.
Mobile two-factor authentication uses phones to replace the traditional key fobs or software-based tokens that were commonly used for remote authentication. When a person tries to log into an online service, a security pin is sent to his or her mobile phone via voice or SMS message, rather than to the token.
Build fast. Deploy faster.
With Twilio, mobile two-factor authentication can be quickly added to any app. A few lines of code is all it takes to dramatically increase security. There are no key fobs to purchase or software to install, and it costs just pennies per message.
"We’re very confident in the solution we developed to protect sensitive information and prevent fraud, and we couldn’t have done that successfully without Twilio on the back end."
