Use Multiple GitHub Accounts on Same Machine

A quick and dirty way

git clone:

git clone https://github.com/<REPO_OWNER>/<REPO>.git

Method 1: Execute commands

git config --local user.name COMMITER_NAME

# NOTE: Do not forget the quotes "" around email!
git config --local user.email "COMMITER_EMAIL"

git remote set-url origin https://<COMMITTER_NAME>:<PAT>@github.com/<REPO_OWNER>/<REPO>.git

Method 2: Modify config file

Just modify these settings in .git/config:

[remote "origin"]
    url = https://<COMMITTER_NAME>:<PAT>@github.com/<REPO_OWNER>/<REPO>.git
    fetch = +refs/heads/*:refs/remotes/origin/*
...
[user]
    name = <COMMITTER_NAME>
    email = <COMMITER_EMAIL>

Now we can do some git operations as COMMITER_NAME ...

git add -u
git commit -m "<COMMIT_MESSAGES>"
git push
