Twitter acquires password security startup Mitro

The social network buys Mitro and lets it keep operating as is -- the only change is now the startup's code will be open source.

Twitter has acquired a small startup called Mitro, which focuses on password security.

Mitro announced Thursday that it is joining Twitter in its New York office and will be "focusing on a variety of geo-related projects." The company will not be integrated into the social network, but rather keep working on its own products that let several people share passwords to one account.

There will be a few changes, however. Most notably, Mitro is now becoming open source. It released all of its server and client code under the GPL license on Github on Thursday. The company will work with the Electronic Frontier Foundation on this transition to become a "sustainable, community-run project."

"We've been working hard to build a secure, easy-to-use password manager for individuals and groups," Mitro wrote on its website. "We've made great progress and we believe that the community can help us accomplish even more."

The financial terms of the deal have not been disclosed. CNET contacted Twitter for more information, and we will update the story when we hear back.
