I have cloned a public repository which is not owned by me. I made changes to that repository. Now after committing the changes , when i am trying to push i am getting this error--

```
$ git push origin master
remote: Permission to navindian/******.git denied to Arpan619Banerjee.
fatal: unable to access '<github URL of that repo>': The requested URL returned error: 403

```

Pls tell me how can I push the changes. I have taken the userid and password from the owner of the repository.
