For example, I can change my username here on this instance. So long as my email id remains the same, my account is operable.
But GitHub doesn’t allow me to change my username. On top of that, GitHub forces an identifier on you when you create your username.


The app I use shows your user name, but if I go to your profile I see both.
Okay, so they’re the same or different ?
Yours are the same, but they can be different.
Okay. Thanks.
