Buffer, a social sharing app, that has suspended its service last month due to a hack that gave attackers access to post anything on its user's Facebook and Twitter accounts.

Buffer announced that it has learned its lesson from that incident and is now bolstering its security program so that the incident won't repeat itself. The app now features two-step login, which requires users to put in an extra security code each time they log in on the site.

With a two-step login and authentication in place, hackers would have a much harder time accessing into the accounts as they will be needing two factors: an email address and a security code, rather than just one. Such authentication is widely used by other popular tech companies.

Buffer said it is also resetting breached credentials and is further encypting the access keys that enables its system posts on user's social media accounts. It also is forcing its team members to turn on two factor authentication for their own personal and business accounts which they could have done in the first place to avoid all the hassle.
