Git Question

my old username is still in use

I have changed my user and email for git with those commands

git config --global user.name "maa"
git config user.email "maa@gmail.com"


I confirmed the change with

git config --global user.name
git config user.email


and it shows the right names.
However when I push the old user name is used:

git push -u origin master
remote: Permission to maa/brain.git denied to old_user_name.
fatal: unable to access 'https://github.com/maa/brain.git/': The requested URL returned error: 403

Answer

The user.name and user.email settings are only used for commit meta data.

As I can see you are using https transport, so the username is stored somehow. To my mind there are two options:

  1. You are using %HOME%/.netrc
  2. Your username is included in the push-url (like https://username@github.com/...), here you need to update .git/config, e.g. by issuing git remote set-url https://<newusername>@github.com/<newusername>/yourRepo
  3. You are using a git credential helper. Here it depends which one you use (and maybe which OS you use, see for Windows, Mac OS X).

As a general rule you can try the following on the CLI (based on 2), where you replace $credentialhelper with your credential-helper (you can find it using git config credential.helper, for Mac OS X it is likely osxkeychain on Windows it might be wincred or manager):

$ git credential-$credentialhelper erase
host=github.com
protocol=https
