Google have just raised the number of Analytics Accounts you can manage from your account to 100 after it was limited to only 25.
If you still have to go beyond this limit, you can always ask a third party (such as the owner of the website that you need to track) to create the Google Analytics account under his/her login and then just provide you with full administrative access. If you’re granted all four access levels (Manage Users, Edit, Collaborate, and Read & Analyze), you’ll have identical privileges to the account creator.
You can also create another Google login, which would allow you set up an additional 100 Google Analytics accounts, but it’s not considered best practice to fragment your Google Analytics accounts among multiple logins.
