As lots of user uses facebook in mobile , so we will learn first in mobile then further learn in how to change username in desktop ! Unfortunately , When I decided to write blog on this topic I found that I didn’t get any option of editing facebook page or facebook profile from mobile so I think facebook team would have removed this option. So let’s discuss about in desktop version now ! Login to facebook account , and follow the steps carefully and see reference image below for better understanding.
For Facebook Profile
Go to top right side of your facebook id and click on setting see above pic for reference, or you can use shortcut as well , Just click on this https://www.facebook.com/settings. Now you can see, that there is option of username under general category , if not set, than set it as per your wishes. Hope you like it. Jai Ma Jwala
