只要在你最喜欢的编辑器中添加这一行，你就完成了一生

git remote set-url origin https://user-token-of-particular-user@github.com/profile-name/repo-name

可以有多种方法来做到这一点，但以下解决方案为我工作，非常简单。 我不是试图用SSH，我的步骤和解决方案是基于HTTPS。

Create your project DIR on your local machine. Example d:\test_git_multiple_account go to the folder "test_git_multiple_account" Add few files here into the DIR Open Git bash here and run following command a. git init // initialization b. git add , // add c. git commit -m "initial commit" you will get following output : in my case i use to add one python file created from code. **[master (root-commit) d4defd9] initial commit 2 files changed, 4 insertions(+) create mode 100644 .vscode/settings.json create mode 100644 Hello.py** d. git remote add origin <HTTPS repo link> e. git remote -v // check the repo version f. git push origin master it will ask your git hub user name and password via popup screen. you will get the following output Counting objects: 100% (5/5), done. Delta compression using up to 4 threads Compressing objects: 100% (3/3), done. Writing objects: 100% (5/5), 411 bytes | 31.00 KiB/s, done. Total 5 (delta 0), reused 0 (delta 0), pack-reused 0 remote: remote: Create a pull request for 'master' on GitHub by visiting: remote: https://github.com/vishvadeepaktripathi/Hello_Py/pull/new/master remote: To https://github.com/vishvadeepaktripathi/Hello_Py.git * [new branch] master -> master

这将创建一个名为master的新分支。 你可以提交到主分支一旦你改变了分支，在这种情况下，你现有的文件将被删除。所以我建议签入主分支到第一步，然后继续为每个命令，如果你想直接签入主分支。 在第一次登录时，它可能会给你一个错误消息，并再次要求登录名和密码，然后它会将您的更改发布到Git中心。

一旦这样做，你会得到消息到新的拉请求到你的github帐户。 您可以将您的更改从主分支合并到主分支。

我在这里创建了主分支，根据你的选择命名你的分支。 还要附加屏幕截图。 在这里输入图像描述

mishaba链接到http://net.tutsplus.com/tutorials/tools-and-tips/how-to-work-with-github-and-multiple-accounts/上的详细信息对我来说非常有用。

从那一页开始:

$ touch ~/.ssh/config

然后编辑该文件如下所示(每个帐户一个条目):

#Default GitHub
Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa

Host github-COMPANY
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_COMPANY

除了为多个帐户创建多个SSH密钥，您还可以考虑使用相同的帐户电子邮件在每个项目上添加合作者，并永久存储密码。

#this store the password permanently
$ git config --global credential.helper wincred

我用不同的电子邮件设置了多个帐户，然后把相同的用户和电子邮件放在每个帐户作为合作者之一。通过这种方式，我可以访问所有的帐户，无需添加SSH密钥，或切换到另一个用户名，和电子邮件进行身份验证。

这个答案是给初学者的(非git大师)。我最近遇到了这个问题，也许这只是我的问题，但大多数答案似乎需要对git有相当深入的了解。在阅读了包括这个线程在内的几个堆栈溢出的答案后，下面是我需要采取的步骤，以便在GitHub帐户之间轻松切换(例如，假设有两个GitHub帐户，github.com/personal和gitHub.com/work):

Check for existing ssh keys: Open Terminal and run this command to see/list existing ssh keys ls -al ~/.ssh files with extension .pub are your ssh keys so you should have two for the personal and work accounts. If there is only one or none, its time to generate other wise skip this.- Generating ssh key: login to github (either the personal or work acc.), navigate to Settings and copy the associated email.now go back to Terminal and run ssh-keygen -t rsa -C "the copied email", you'll see:Generating public/private rsa key pair. Enter file in which to save the key (/.../.ssh/id_rsa): id_rsa is the default name for the soon to be generated ssh key so copy the path and rename the default, e.g. /.../.ssh/id_rsa_work if generating for work account. provide a password or just enter to ignore and, you'll read something like The key's randomart image is: and the image. done.Repeat this step once more for your second github account. Make sure you use the right email address and a different ssh key name (e.g. id_rsa_personal) to avoid overwriting. At this stage, you should see two ssh keys when running ls -al ~/.ssh again. Associate ssh key with gitHub account: Next step is to copy one of the ssh keys, run this but replacing your own ssh key name: pbcopy < ~/.ssh/id_rsa_work.pub, replace id_rsa_work.pub with what you called yours.Now that our ssh key is copied to clipboard, go back to github account [Make sure you're logged in to work account if the ssh key you copied is id_rsa_work] and navigate toSettings - SSH and GPG Keys and click on New SSH key button (not New GPG key btw :D) give some title for this key, paste the key and click on Add SSH key. You've now either successfully added the ssh key or noticed it has been there all along which is fine (or you got an error because you selected New GPG key instead of New SSH key :D). Associate ssh key with gitHub account: Repeat the above step for your second account. Edit the global git configuration: Last step is to make sure the global configuration file is aware of all github accounts (so to say). Run git config --global --edit to edit this global file, if this opens vim and you don't know how to use it, press i to enter Insert mode, edit the file as below, and press esc followed by :wq to exit insert mode: [inside this square brackets give a name to the followed acc.] name = github_username email = github_emailaddress [any other name] name = github_username email = github_email [credential] helper = osxkeychain useHttpPath = true

完成了!现在，当尝试从一个回购中推或拉，你会被问到哪个GitHub账户应该与这个回购链接，它只被问到一次，本地配置将记住这个链接，而不是全局配置，所以你可以在不同的回购上工作，链接到不同的账户，而不必每次编辑全局配置。

你可以使用Github桌面。在这里，你只需要在本地克隆存储库，并使用Github Desktop管理代码。
