Twitter this week is a couple new features to Digits -- its service that helps developers integrate simpler, password-free login options into third-party mobile applications. They include a friend finding function and two-step verification, TechCrunch reports. “While already Digits was offering a more secure way for users to log into apps by using their phone number instead of a username and password combination … the option to include two-step verification provides another layer of security.” 

Nextdoor -- a social network for geographically close contacts and affiliations -- just raised $110 million at a valuation of $1.1 billion. “The investors seem to believe that there is more money to be had in small -- neighborhood-size – communities,” The New York Times reports. Yet, “Many Internet companies, including AOL, Google and Foursquare, have already homed in on this market, with mixed success.” 

Facebook’s Oculus virtual reality unit has reportedly poached Mary Lou Jepsen, a high-ranking executive at Google X. Reporting directly to Google co-founder Sergey Brin, Jepsen spent the last three years running the Display Division at Google’s experimental technology unit, Re/Code reports, citing sources. “Jepsen specialized in digital displays at Google, which is certainly in the same vein as virtual reality,” it notes. 

Facebook famously got its start at Harvard. Could the next great social network come from within the rarified walls of Goldman Sachs? That’s what the investment bank has planned with Symphony -- a messaging and social service that is already popular among employees and is expected to make a public debut by July. Give the service a fighting chance, a consortium of 15 banks (include Goldman) have already invested $66 million in Symphony, The New York Post reports, citing sources.
