I have a google account based on an email name that I don't really like(used native spelling instead of the English one and now live abroad). I have LOTS of things tied to it though, (Android, drive etc) plus apps that login with Google authentication.
I exclude 3rd party apps that used directly the email for making an account, since not much can be done for that.
I would like to start using a new email with a better name for everything, or have both accounts kind of managed in parallel, without need to think which of the two I am really using.
It must be such a common need, but can't find anything conclusive online... Please help :)
