本文翻译自：GitHub: invalid username or password

I have a project hosted on GitHub. 我有一个在GitHub上托管的项目。 I fail when trying to push my modifications on the master. 我试图推动我对主人的修改时失败了。 I always get the following error message 我总是收到以下错误消息

Password for 'https://[email protected]': 
remote: Invalid username or password.
fatal: Authentication failed for 'https://[email protected]/eurydyce/MDANSE.git/'

However, setting my ssh key to github seems ok. 但是，将我的ssh密钥设置为github似乎没问题。 Indeed, when I do a ssh -T [email protected] I get 的确，当我做一个ssh -T [email protected]我明白了

Hi eurydyce! You've successfully authenticated, but GitHub does not provide shell access.

Which seems to indicate that everything is OK from that side (eurydyce being my github username). 这似乎表明从那一方来说一切正常（eurydyce是我的github用户名）。 I strictly followed the instructions given on github and the recommendations of many stack discussion but no way. 我严格遵循github上给出的指令和许多堆栈讨论的建议，但没办法。 Would you have any idea of what I may have done wrong? 你知道我做错了什么吗？

https://[email protected]/eurydyce/MDANSE.git is not an ssh url, it is an https one (which would require your GitHub account name, instead of ' git '). https://[email protected]/eurydyce/MDANSE.git不是一个ssh url，它是一个https（需要你的GitHub帐户名，而不是' git '）。

Try to use ssh://[email protected]:eurydyce/MDANSE.git or just [email protected]:eurydyce/MDANSE.git 尝试使用ssh://[email protected]:eurydyce/MDANSE.git或者只是[email protected]:eurydyce/MDANSE.git

git remote set-url origin [email protected]:eurydyce/MDANSE.git

The OP Pellegrini Eric adds: OP Pellegrini Eric补充道：

That's what I did in my ~/.gitconfig file that contains currently the following entries [remote "origin"] [email protected]:eurydyce/MDANSE.git 这就是我在~/.gitconfig文件中所做的，其中包含当前以下条目[remote "origin"] [email protected]:eurydyce/MDANSE.git

This should not be in your global config (the one in ~/ ). 这不应该在你的全局配置中（ ~/ ）。
You could check git config -l in your repo: that url should be declared in the local config: <yourrepo>/.git/config . 您可以在您的仓库中检查git config -l ：该url应该在本地配置中声明： <yourrepo>/.git/config 。

So make sure you are in the repo path when doing the git remote set-url command. 因此，在执行git remote set-url命令时，请确保您处于repo路径中。

When using the https:// URL to connect to your remote repository, then Git will not use SSH as authentication but will instead try a basic authentication over HTTPS. 使用https:// URL连接到远程存储库时，Git不会使用SSH作为身份验证，而是尝试通过HTTPS进行基本身份验证。 Usually, you would just use the URL without a username, eg https://github.com/username/repository.git , and Git would then prompt you to enter both a username (your GitHub username) and your password. 通常，您只需使用不带用户名的URL，例如https://github.com/username/repository.git ，然后Git会提示您输入用户名（您的GitHub用户名）和密码。

If you use https://[email protected]/username/repository.git , then you have preset the username Git will use for authentication: something . 如果您使用https://[email protected]/username/repository.git ，那么您已预设Git将用于身份验证的用户名： something 。 Since you used https://[email protected] , Git will try to log in using the git username for which your password of course doesn't work. 由于您使用了https://[email protected]将尝试使用您的密码当然不起作用的git用户名登录。 So you will have to use your username instead. 因此，您必须使用您的用户名。

The alternative is actually to use SSH for authentication. 替代方案实际上是使用SSH进行身份验证。 That way you will avoid having to type your password all the time; 这样你就不必一直输入你的密码; and since it already seems to work, that's what you should be using. 并且因为它似乎已经起作用，所以你应该使用它。

To do that, you need to change your remote URL though, so Git knows that it needs to connect via SSH. 为此，您需要更改远程URL，因此Git知道它需要通过SSH连接。 The format is then this: [email protected]:username/repository . 格式如下： [email protected]:username/repository 。 To update your URL use this command: 要更新您的URL，请使用以下命令：

git remote set-url origin [email protected]:username/repository

After enabling Two Factor Authentication (2FA), you may see something like this when attempting to use git clone , git fetch , git pull or git push : 启用双因素身份验证（2FA）后，您可能会在尝试使用git clone ， git fetch ， git pull或git push时看到类似的内容：

$ git push origin master
Username for 'https://github.com': your_user_name
Password for 'https://[email protected]': 
remote: Invalid username or password.
fatal: Authentication failed for 'https://github.com/your_user_name/repo_name.git/'

Why this is happening 为什么会这样

From the GitHub Help documentation : 从GitHub帮助文档 ：

After 2FA is enabled you will need to enter a personal access token instead of a 2FA code and your GitHub password. 启用2FA后，您需要输入个人访问令牌，而不是2FA代码和GitHub密码。

... ...

For example, when you access a repository using Git on the command line using commands like git clone , git fetch , git pull or git push with HTTPS URLs, you must provide your GitHub username and your personal access token when prompted for a username and password. 例如，当您使用Git git clone ， git fetch ， git pull或带有HTTPS URL的git push等命令在命令行上使用Git访问存储库时，在提示输入用户名和密码时，必须提供GitHub用户名和个人访问令牌。 。 The command line prompt won't specify that you should enter your personal access token when it asks for your password. 命令行提示符不会指定您在要求输入密码时应输入个人访问令牌。

How to fix it 如何解决它

1. Generate a Personal Access Token . 生成个人访问令牌 。 (Detailed guide on Creating a personal access token for the command line .) （有关为命令行创建个人访问令牌的详细指南。）
2. Copy the Personal Access Token. 复制个人访问令牌。
3. Re-attempt the command you were trying and use Personal Access Token in the place of your password. 重新尝试您尝试的命令，并使用个人访问令牌代替您的密码。

just try to push it to your branch again. 只是尝试再次将其推送到您的分支机构。 This will ask your username and password again, so you can feed in the changed password. 这将再次询问您的用户名和密码，因此您可以输入更改的密码。 So that your new password will be stored again in the cache. 这样您的新密码将再次存储在缓存中。

If like me you just updated your password and ran git push to run into this issue, then there's a super easy fix. 如果像我一样你刚刚更新了你的密码并运行git push来解决这个问题，那么就有一个非常简单的解决方法。

For Mac users only. 仅限Mac用户。 You need to delete your OSX Keychain access entries for GitHub. 您需要删除GitHub的OSX Keychain访问条目。 You can do it via terminal by running the following commands. 您可以通过运行以下命令通过终端执行此操作。

Deleting your credentials via the command line 通过命令行删除凭据

Through the command line, you can use the credential helper directly to erase the keychain entry. 通过命令行，您可以直接使用凭证帮助程序擦除钥匙串条目。

To do this, type the following command: 为此，请键入以下命令：

git credential-osxkeychain erase
host=github.com
protocol=https

# [Now Press Return]

If it's successful, nothing will print out. 如果成功，则不会打印出任何内容。 To test that it works, try and clone a repository from GitHub or run your previous action again like in my case git push . 要测试它是否有效，请尝试从GitHub克隆存储库，或者像我的git push一样再次运行您之前的操作。 If you are prompted for a password, the keychain entry was deleted. 如果系统提示您输入密码，则会删除钥匙串条目。
