As my clients grow in number I find it harder and harder to maintain an up-to-date record of all server-names, user-names, passwords, MySQL databases etc. etc. I am contemplating writing a database app that will store such information together with other project related data. One advantage of such a database would be that I could simply create reports in the form of data sheets which I could send my clients when they ask for it. But I was wondering how others keep their technical administration. Are there any existing tools out there? Or do you just write/print the info on paper?
