Digital note-taking service Evernote was forced to reset its 50 million-plus users’ passwords after suffering an unauthorized breach on March 2. Thursday, less than three months on from that incident, it is beefing up account security measures with three new measures, including two-factor authentication, which will initially go live to its premium users. In the aftermath of the March hack, the company promised that two-step authentication would introduced for all registered users “later this year” and the security measure — which uses SMS to verify the identity of a user — is being introduced, alongside ‘access history’ and ‘authorized applications’ measures. The two-step verification — a variant of which was adopted by Twitter just last week — is the headline feature, and it will work in the same way that it does with Google and other services.
