If you have the Standard, Plus, Pro, or Premium plan you have the ability to give multiple people access to your Spring Metrics account. To give another person access, you can create a user account for them.
Begin by clicking on the Settings link at the top of the application. Then click on the Site Settings link:
On the right side of the page, click "Add another user".
You should see a form expand - fill in the required information and click "Create".
Now your new user will be able to log in with the credentials you entered. Note that this user will also now receive daily email reports with analytics data.
