有时候准备pull的时候却发现密码怎么输也输不对，提示的信息是没有权限或者密码错误，如下：

$ git pull
git@git.***.com's password:
Permission denied, please try again.
git@git.***.com's password:
Permission denied, please try again.
git@git.***.com's password:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

如果出现以上类似的报错提示的话不妨试一下生成ssh－key的方法。步骤如下
在终端输入

ssh-keygen -t rsa -C "self name"    //self name为用户名

如果执行成功。返回

Generating public/private
rsa key pair.

Enter file in which to save the key (/home/forwhat.cn/.ssh/id_rsa):

后面的几步提示都可以直接回车

$ ssh-keygen -t rsa -C "self name"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/*****/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/*****/.ssh/id_rsa.
Your public key has been saved in /c/Users/*****/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:ut9Y****Wwg*******8PYsvs4v+iDlk8xXqb++YkmM self name
The key's randomart image is:
+---[RSA 2048]----+
|    .o.          |
|     ooo         |
|    . *.         |
|.  . o o         |
|... .  S        |

|o.+oo . + o      |
|++Eo.oo O       |
|=BO+=+++=O..      |
+----[SHA2756]-----+
(敏感已处理)

把刚才上面显示的存储的地址放在vi编译器里运行会生成如下代码

vim /c/Users/*****/.ssh/id_rsa.pub（你的公钥）
//例
ssh-rsa AAAAB3NzaC1..............vvo1+xSKvIXLhjqvoHoyoj8oDkOycZeaOASJhbOT+6xvTuGutM/3SDoFkFzHjL34CnGLyX
 sell name

添加已生成的秘钥 ssh-add ‘私钥Url’

 ssh-add /c/Users/*****/.ssh/id_rsa

如果出现

Could not open a connection to your authentication agent.

则：

eval `ssh-agent -s`

或清空

known_hosts 文件

git config 可查看所有git配置
git config user.email 查看当前用户邮箱（查看其它以此类推）
