How to change google + user name?

I want to change my G+ user name ... Hw to do it?

 

From your Google+ Profile page click the "Edit Profile" button at the top right, then click on your name displayed at the top of the profile page.

 

If you are using Gmail account for your Google account, you cant change your username. you will need to delete gmail from your account and use a non-gmail address for your google account.

But if you are not using your gmail address then you can change your username at any time.

To change the email address on your account, just follow these steps:

1. Visit the Google Accounts homepage.
2. Sign in to your account.
3. Click Change in the Email addresses section.
4. Enter your new email address and your current password.
5. Click Save email address.

Google will then send you a verification mail with a link. Click on the link and complete the process.
