Evernote is a suite of software and services designed for writing, collecting, finding and presenting work across a variety of devices and formats. Its software is specifically designed to be simple, accessible and available everywhere.
As of May 2014, Evernote is being used by more than 100 million people in a little more than six years since its launch.
In 2013, Evernote began a wide-ranging review of its security measures to ensure the integrity and overall experience of its services.
In order to protect their global accounts from compromise, beyond the traditional username and password, Evernote decided to offer phone-based two-factor authentication to all user accounts.
During the vendor analysis process, Evernote was looking for several specific qualities, such as: global coverage, ease of implementation and overall experience.
"We were looking at several vendors, but TeleSign won out because of their demonstrated security expertise, the quality of their global SMS authentication offering, and because they understood the importance of the overall experience. TeleSign worked closely with us to ensure our UI/UX provided the best experience possible and would be easily adopted,” commented Dave Engberg, CTO, Evernote.
Since deploying two-factor authentication, .07% of their free users and a 1.09% of Premium users have the feature enabled.In addition to TeleSign's two-factor authentication offering, Evernote also deployed TeleSign's PhoneID to identify if a phone is SMS-enabled or not.
Evernote uses PhoneID to confirm that, if a user has requested an SMS, they have provided a phone number that can actually receive an SMS. If their phone is not SMS-enabled, users are prompted to provide a new number, instead of waiting for an authentication SMS that will never come – a small but critical step to improve overall user experience.
