Popular media-saving service Evernote has stepped up its security after a recent breach in which users' emails and passwords were leaked. The company is now offering two-factor verification to its premium users to make sure that when someone signs into your account, it's really you.
The hack, in March, did not appear to expose any critical information like financial data, but just in case, Evernote's 50 million users were warned of the attack and their pssswords reset.
Two-factor verification or authentication improves on using just passwords by requiring that whoever logs in also input a code sent to their mobile phone. The idea is that by using both something only you should know (your password) with something only you should have (your phone) makes things very difficult for potential hackers. Twitter said last week it is starting two-factor authentication, and it is something used by Google, Facebook and Microsoft.
Of course, the two-factor authentication measures would not have prevented the hack of Evernote itself, but is meant to protect users from the fallout of attacks like that. Even if a hacker had your username and password, they couldn't log in, since the additional code they'd need would go to your phone and not theirs. Not only that, but you'd be alerted instantly that someone other than you was trying to access your account.
To get this extra layer of security, make sure your Evernote-related apps are up to date, then log in using the browser and head to Account Settings, where the option will present itself.
It's only available to premium and business users at the moment, but will expand to all free users once the company thinks the system is ready to support tens of millions of people.
