Ask HN: what do you use for shared PW storage?

What does your team/startup use for secure+encrypted, shared secret info (like PW) storage? I'm looking for something that is role based or has the ability to explicitly give user X access to asset Y. Example I have a pingdom.com l/p that I 3 of my co-workers to be able to use.

I don't mind hosting the tool. I've found https://www.passpack.com/online/ but am hesitant to trust someone else with my sensitive data.
