Evernote enabled two-step verification for its Evernote Premium and Evernote Business users in May, and now the extra security layer is available to the rest of its user base. When enabled, users will need both a generated code from a smartphone as well as a username and password in order to log into the service. The feature comes after a security breach earlier this year that prompted the company to force all users to change their passwords and expedited the development of advanced security features. Unpaid users will be required to download an authenticator app, such as Google Authenticator, in order to generate the login code, while premium and business users can choose to have the code delivered as a text message.
