Exclusive: Snowden persuaded other NSA workers to give up passwords - sources

Snowden may have persuaded between 20 and 25 fellow workers at the NSA regional operations center in Hawaii to give him their logins and passwords by telling them they were needed for him to do his job as a computer systems administrator, a second source said.

The revelation that Snowden got access to some of the material he leaked by using colleagues' passwords surfaced as the U.S. Senate Intelligence Committee approved a bill intended in part to tighten security over U.S. intelligence data.
