Hi There, thank you for reaching out. Currently, there is no way to change your account name to what you want. It is just the way it is. HOWEVER, you can edit your username or account on your iPhone/Android. Please follow the steps below.
Step 1: Tap Home, then click settings Step 2: Click to view your profile Step 3: Click Edit Profile Step 4: Click your display name and change it Step 5: Once you have renamed your profile click save.
If you can not edit your account from the steps above, what you can do is link your Spotify account to Facebook. However, your friends will only be able to see your real name and not your Spotify account name. Hope this helps.
