GitHub credentials problem at install via composer

Hi all.

I have tried to install the basic yii2 with composer, and I got the following error message:

I added my github account and password, but It was rejected. :(

How can I solve this problem?

This is probably an issue with your composer setup/config, or perhaps your github account and git config, but likely not a problem with Yii 2.

You also may want to keep your github password out of your codebase.
