Where to modify the pseudonym used to rate Android apps?

Question

I am currently rating android applications that I downloaded with the username firstname.lastname where firstname and lastname are mine.

However, I would like to put a pseudonym on it because my real name reveals to everybody the device I am using, which should be private. Currently, my rating looks like this one:

firstname.lastname on May 22, 2012 (Samsung Galaxy S2 with version 1.0)

I looked into my public profile of Google+, but I cannot find something which looks like firstname.lastname. I looked on the Google Play website, but I did not find related preferences.

Where can I change this name? Is it in the device itself or what?

Answer 1

Change your nickname in your Google account settings.

Answer 2

Ok, I finally found it. I need to click on "edit/modify" close to the e-mail addresses in the google account setting

https://www.google.com/settings/

Then the hidden nickname option appears. Thank you for your suggestions.
