Open Spotify and log in to your account
Go to your profile or account settings
Check whether you are using a Spotify username or display name
If you want to change your display name, edit it in your profile settings
Save the changes
If you want to change your Spotify username, know that Spotify does not allow changing the original username
Create a new account if you need a different Spotify username
Use Facebook, Apple, or Google login if you want to change the login method instead of the username
