How can I track my 30 sites without 30 logins

[ecomsolutions]

Each site has its own google account, login and codes so clients can access as their own sites. But as webmaster can I open an account to track ALL these sites (and get them listed in the drop down on my account) as well?
I was thinking of adding an extra set of code on each site for me so every sites has 2 tracking codes... one for the cleint and one for me... would that work?
Is there a better way? I do not want to upset Mr Google.

I think you can. Create another account and add your 30 sites on your new account.

Thanks. Does this mean I have to create an extra set of coding for each account so one code goes to client's account dashboard and one set goes to my account dashboard?

Only one code. You can create more than one login to each account with limited access. That should be the best option. Create separate limited accounts for clients, from within your main control panel.
