git 更新密码之后出现异常（雾）
git 更新密码之后出现了问题（雾）
记录一下今天的沙雕操作
github密码太简单被强行更新，然后git clone按照平时那样用，输入新的密码，提示没有权限
wen@xiaobao /c/1111111/home
$ git clone [email protected]:XXXXXXXX/XXXX.git
Cloning into 'cppPractice'...
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
参考了下搜到的在 控制面板\用户帐户\凭据管理器，Windows凭据改掉git的密码。
然而还是不行。是不是ssh的问题？把.ssh里面的id_rsa.pub内容拷贝到github网页上的settings->ssh->SSH and GPG keys->SSH keys->New SSH key里面，提示Key is already in use。
找了个测试ssh连接的命令：
wen@xiaobao /c/1111111/home
$ ssh -T [email protected]
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
[email protected]: Permission denied (publickey).
照常输了三次新的github密码，Permission denied (publickey),换了个长一点的命令
wen@xiaobao /c/1111111/home
$ ssh -vT [email protected]

太长了看不懂，大概就是连接成功了，不是没有reply的问题。
ssh目录下id_rsa，id_rsa.pub，known_hosts仨文件齐全，也不是缺少私钥id_rsa问题。
ssh 没有权限,看到这样一句话：
难道说私钥id_rsa的密码不是github的密码？？？试了一下之前的ssh密码。

只输了一次密码，原来让我输三次密码是因为密码输错错了…
一句话概括：
wen@xiaobao /c/1111111/home
$ ssh -T [email protected]
Enter passphrase for key '/c/Users/wen/.ssh/id_rsa':
Hi thenamehasbeentake! You've successfully authenticated, but GitHub does not provide shell access.

搞了半天原来是理解错了passphrase for id_rsa的含义，这个密码跟git的账号密码不是同一个，当初配环境的时候没仔细看，弄出了这样让人啼笑皆非的睿智操作。
震惊，git密码更新导致ssh失效？ssh配置连接正常却permission denied？这背后到底是道德的沦丧还是人性的扭曲。
总结一下：git密码更新之后，大概只需要改一下凭据就够了…
