Note
As of August 24, 2022, Sales Analytics is no longer accessible via an account nickname. To access Sales Analytics, users MUST have a primary (aka "master") account.
If you do not have a master account, you must create one to access this feature. If you do have a master account, access it user your email username. From there you can link your account nickname to view the Sales Analytics data for it.

What if I don't remember what my master account email is?
If you have forgotten what email address you used for your master account, you can find it in your account nickname under the Account Settings tab.
