您所需要做的就是使用多个SSH密钥对配置您的SSH设置。

这个链接很容易理解(谢谢Eric): http://code.tutsplus.com/tutorials/quick-tip-how-to-work-with-github-and-multiple-accounts--net-22574 生成SSH密钥(Win/msysgit): https://help.github.com/articles/generating-an-ssh-key/

第一个环节的相关步骤:

Generate an SSH-key: ssh-keygen -t ed25519 -C "john@doe.example.com" Follow the prompts and decide a name, e.g. id_ed25519_example_company. Copy the SSH public-key to GitHub from ~/.ssh/id_ed25519_doe_company.pub and tell ssh about the key: ssh-add ~/.ssh/id_ed25519_doe_company Create a config file in ~/.ssh with the following contents: Host github-doe-company HostName github.com User git IdentityFile ~/.ssh/id_ed25519_doe_company Add your remote: git remote add origin git@github-doe-company:username/repo.git or change using: git remote set-url origin git@github-doe-company:username/repo.git

此外，如果你正在使用多个使用不同角色的存储库，你需要确保你的各个存储库有相应的用户设置覆盖:

设置用户名，电子邮件和GitHub令牌-覆盖个人回购的设置 https://help.github.com/articles/setting-your-commit-email-address-in-git/

注意: 有些人可能需要不同的电子邮件用于不同的存储库，从git 2.13开始，你可以通过编辑全局配置文件在目录的基础上设置电子邮件:~/。Gitconfig使用这样的条件:

[user]
    name = Default Name
    email = defaultemail@example.com

[includeIf "gitdir:~/work/"]
    path = ~/work/.gitconfig

然后是特定于工作的配置~/work/。Gitconfig看起来是这样的:

[user]
    name = Pavan Kataria
    email = pavan.kataria@example.com

谢谢@alexg在评论中告诉我这件事。

将github中的认证方式由SSh修改为HTTP。这样它就不会关心你是否登录了你的工作github帐户，你试图远程与你的个人github帐户(它有不同的凭据，而不是你目前登录到你的本地机器)交互。

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。

选项0:你不想乱搞操作系统设置..你只是想为一次回购提交一个不同的github账户，使用不同的公钥。

解决方案:

create the new key: ssh-keygen -t rsa -b 4096 -f ~/.ssh/alt_rsa add the key to the keyset: ssh-add -K ~/.ssh/alt_rsa copy and add the pub key to the github account: (see github instructions) test the key with github: ssh -i ~/.ssh/alt_rsa T git@github.com clone the repo using the git protocol (not HTTP): git clone git@github:myaccount... in the cloned repo: git config core.sshCommand "ssh -i ~/.ssh/alt_rsa -F /dev/null" git config user.name [myaccount] git config user.email [myaccount email] now you should be able to git push correctly without interferring with your everyday git account

另一种更简单的方法是使用多个桌面应用程序，就像我在做什么，使用帐户A在Github桌面，而使用帐户B在Github Kraken

2023年更新:

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。
