Username and Password type CRM?!

Does anybody know of any type of either hosted or self hosted or Desktop Software, that I can use if I need to Keep ( Build )
a Database of some kind that Have My client's Username and Passwords for the software that I sell.

So if a client phones I can just launch this software or site, Log In, then Search for some kind of field, like their email or company name
then find their profile and then see their username and password and then pass this on to them.

Maybe even email them a Customized report with all the details.

I was thinking something in the line of a ISP Management type of software, or something similar maybe a type of CRM that has this
functions.

Im a little worried that Im going to start to loose client details etc because currently I create their report with excel and then save it as a pdf.


But Im sure there must be something better.

Thanks all.

Bullseye!!

Anyone ? Please ? Seems there is no such thing available ? I have search google like crazy but am not entirely sure I use the correct Keywords.
I don't find any useful results.
