Github user prasadwagle commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/856#issuecomment-217516417 @Leemoonsoo I added "Save user credentials in a file with encryption" TODO in [#860](https://github.com/apache/incubator-zeppelin/pull/860). We decided to hold off on this feature since our security team told us that the risks were high (even with encryption) and we would have to deal with regulatory requirements. I will implement this feature with an option to turn it off.
