I have a Gmail account created using my name as
firstname.lastname@example.org. But I don't like it, and I want to login using
email@example.com. Surely this is obviously possible (by using the feature "Add another account you own"). Also,
firstname.lastname@example.org can be made the default sending address. But in the Gmail page, on the top right corner, clicking on the user icon shows that old
email@example.com as my email address. I don't want that.
So is there any way to remove the email address that was originally used to create the email account (
firstname.lastname@example.org in my case), and use an alias (
email@example.com) as the email address? In fact, I want to do this only because I don't like to see
firstname.lastname@example.org as my email address on the top right corner, and in all other places where my email address is displayed.
