Server / websites information management system

Just like I use RoboForm to manage logins, passwords, forms etc…, is there any plugin or such that we can use to manage and keep track of the server / websites information, like control panel logins, FTP, MySQL, SSH, etc…

I know I can custom develop this using CustomPress plugin but the biggest hurdle is that the entire data should be encoded such that only the script / plugin can decode it.

I really need one such because we have more than 20 servers & 50+ websites and its becomes very difficult to keep track of all this.

I choose WP for this so that the information is stored online and is handy even if I am accessing it from anywhere in the world. Seems to be somewhat risky but I am sure there will be some work around for this.
