Note-taking service Evernote has become the latest online vendor to offer users two-factor security authentication features.
The company said that its service, which allows users to store notes, reminders and other important pieces of data, would be rolling out the feature as part of a larger security update which will also include the ability access user history and authorise outside applications.
Under the new system, customers will be able to link their accounts with a mobile device or number. When the user accesses a service which requires an account name and password, a third dialogue will also require the input of a numerical code sent to the device via SMS.
“This will usually only happen when you log into Evernote Web or install it on a new device,” the company explained.
“This combination of something you know (your password) and something you have (your phone) makes two-step verification a significant security improvement over passwords alone.”
Evernote has been under pressure to beef up its security protections since early May, when a breach allowed attackers to lift user credentials and forced the company to require users to reset their account information.
The use of two-factor authentication has long been advocated by security experts who view the method as a means for thwarting social engineering attacks such as phishing operations which can easily gather usernames and passwords.
While it has been shown theoretically possible to intercept the SMS transmissions via malware-born 'man in the middle' attacks, such operations have been shown to be complex and extremely difficult to carry out on a large scale.
