How to change my username on Deezer Community?

Hi ​@alejandromesquita !

Your Deezer Community username is tied directly to your main Deezer account profile.

Log in via a web browser on Deezer or an Android/Desktop app, go to Settings > Account Management, select your profile, type your new username, and save.

 But ,you cannot change it directly from an iOS app .You must log into Deezer using a web browser.
