不像其他答案，在那里你需要遵循几个步骤来使用两个不同的github帐户从同一台机器，对我来说，它在两个步骤。

你只需要:

1)在~/下为您的每个帐户生成SSH公私钥对。使用不同的名称和SSH位置

2)在“设置”中，将生成的公钥添加到对应的帐号“>> SSH和GPG密钥>> SSH新密钥”。

使用实例生成SSH公私钥对。

cd ~/.ssh
ssh-keygen -t rsa -C "email@work.com" -f "id_rsa_WORK"
ssh-keygen -t rsa -C "email@gmail.com" -f "id_rsa_PERSONAL"

作为上述命令的结果，id_rsa_WORK和id_rsa_WORK。pub文件将为您的工作帐户(ex - git.work.com)和id_rsa_PERSONAL和id_rsa_PERSONAL创建。Pub将为您的个人帐户(ex - github.com)创建。

创建之后，从每个公共(*.pub)文件复制内容，并对每个帐户执行步骤2。

PS:没有必要为~/下的每个git帐户创建一个主机条目。Ssh /配置文件，如在其他答案中提到的，如果您的两个帐户的主机名不同。

以防你不想弄乱~/。这里提到的Ssh /config文件，你可以运行git config core。ssh -i ~/.使用实例Ssh /custom_id_rsa”，你想从一个不同的帐户提交。

其余的设置是相同的:

使用SSH -keygen -t rsa -f ~/为第二个帐户创建新的SSH密钥。SSH -f ~/.ssh/custom_id_rsa 使用您的其他帐户登录github，转到https://github.com/settings/keys，并粘贴~/.ssh/custom_id_rsa.pub的内容 确保您使用SSH而不是HTTPS作为远程url: git remote set-url origin git@github.com:upstream_project_teamname/upstream_project.git

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。

您应该也不应该使用一些常见凭证推送到项目。在新机器上启动后，按照以下步骤正确设置和使用gitlab凭证:

在计算机上创建公共/私有SSH密钥 复制粘贴公钥到gitlab/github UI界面(任何通过CMD行提示如何操作的人都可以获得免费啤酒…) 请确保您通过git而不是HTTP url克隆回购 设置git别名，以避免git命令经常输入相同的前缀 在git提交期间，总是使用author和e-mail标记 使用git正常你会这样做

这一切如下:

 # create the public / private key credentials on that specific machine
 ssh-keygen -t rsa -b 4096 -C "<<you>>@org.net" -f ~/.ssh/id_rsa.<<you>>.`hostname -s`

 # setup your public key in the gitlab ui 
 cat ~/.ssh/id_rsa.<<you>>.`hostname -s`

 # make sure you clone the repo via the git and not http url
 git clone git@git.in.org.net:org/some-repo.git

 # set the git alias to avoid constant typing of the repeating prefix to the git cmd
 alias git='GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa.<<you>>.`hostname -s`" git'

 # during git commit ALWAYS use the author and e-mail flags
 git add --all ; git commit -nm "$git_msg" --author "YourFirstName YourLastName <you@phz.fi>"

 # use git as normal
 git fetch --all; git pull --all 

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。

相反，您只需将新的电子邮件id添加到您的个人git帐户。这样您就不需要添加另一个SSH密钥。只需按以下步骤配置新邮箱即可 Git配置——全局用户。电子邮件newemail。然后你就可以复制那个回购了。
