I would never store sensitive data like passwords there. Evernote is a great service, but doesn’t encrypt your data on their servers, unless that has changed in the past couple of years. I think Evernote takes security seriously, but I’ve never gotten the feeling that it is their highest priority. They also have had at least one security breach:

If you’re going to share passwords, I’d recommend a tool like 1Password or LastPass. They encrypt your passwords, so even if you were hacked, it would be very difficult (possibly impossible) for any harm to come of the intrusion. The developers of 1Password have a tutorial about how to share groups of passwords:
