Oakland To Tech: Please Don’t Screw This Up Like Last Time

“I think the thing that comes to mind when people think about tech coming into Oakland, it’s not that they dislike tech,” Jones told me last month.

Another fast-growing program called MissionBit puts dozens of volunteer programming instructors in the San Francisco Unified School District’s after school programs.

Clef Offers Two-Factor Authentication Without All The Codes

Oakland-based Clef has designed a two-factor authentication system that cuts out the codes and the time spent entering them. One popular defense you can use to bolster data security on most services is two-factor authentication. On your phone, you open a Clef app, verify it’s you with Touch ID (or a PIN), and then point your phone’s camera at the screen. More than 40,000 sites have signed up to use their two-factor authentication system, and having just graduated from StartX’s most recent class of companies, Clef is now working on growing its engineering and marketing staff to bring in more clients with bigger user bases. By scanning the wave form, Clef shows that you’re actually sitting there in front of the app, and it’s all done in seconds.
