How to change your username (or real name):

Changing your name(s) is easy! Visit your Twitter account settings to change either your real name and/or username.

1. Log in to Twitter
2. From the upper right hand drop-down menu, click Settings
3. Change the name listed in your username field on the first page you see there.
4. To change your real name, go to the Profile tab of these settings, and type in a new name.
5. Save your changes.

NOTE: Changing your username will not affect your existing followers, direct messages, or @replies. They will simply see a new username next to your picture when you update. It is advisable to send out an update to your followers before you change your username, because any replies or messages sent to your old username will not be associated with your account once you've changed to your new username.
What's the difference between your real name and your user name?

* Your username appears in your profile URL and is unique to you. Usernames are used for login, @replies, direct messaging, and more. Your username appears alongside your profile image in friends' timelines each time you update, and we also include it in all outgoing text messages.
* Your real name is your full name, displayed in your profile page and used to identify you to friends. This can be helpful if your username is something mysterious, such as @neongolden, or @meangrape. Some people choose to put something other than a name in that field, such as their company or business name.
