Git 推送至 Github 时提示：The authenticity of host ‘github.com (52.192.72.89)’ can’t be established.ECDSA key fingerprint is SHA256:.，在 Windows 10 中配置 GitHub 的 SSH key，生成新的 Personal access token
1、在执行命令时：git push -u origin master，提示：The authenticity of host ‘github.com (52.192.72.89)’ can’t be established.ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM.。如图1
2、通过 TortoiseGit 推送，仍然报错：Logon failed, use ctrl+c to cancel basic credential prompt.。如图2
3、远程：2021 年 8 月 13 日移除了对密码身份验证的支持。请改用个人访问令牌。远程：请参阅 https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ 了解更多信息。从 2021 年 8 月 13 日开始，我们将在对 Git 操作进行身份验证时不再接受帐户密码，并将要求使用基于令牌的身份验证。
4、配置两步验证，参考网址：https://docs.github.com/cn/authentication/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication 。
5、参考网址：https://www.jianshu.com/p/9317a927e844 。生成一个新的 SSH 密钥。打开 Git Bash，输入如下命令，然后连续按三个回车即可：ssh-keygen -t rsa -C “shuijingwanwq@163.com”。密钥保存路径：/c/Users/Administrator/.ssh。id_rsa 是密钥，id_rsa.pub 是公钥。如图3
6、将 SSH 私钥添加到 ssh-agent，在后台启动 ssh-agent，将 SSH 私钥添加到 ssh-agent。如图47、将 SSH 公钥添加到 GitHub 账户，先复制 SSH 公钥的完整内容(/c/Users/Administrator/.ssh/id_rsa.pub)。如图58、将公钥添加到 GitHub 账号，先打开 Github SSH 令牌管理页面：https://github.com/settings/keys ，然后把你刚刚复制的令牌按照下图示例添加。如图6
9、测试连接，打开 Git Bash 输入：ssh -T git@github.com 。在 PowerShell 中执行仍然报错，但是总体是成功了。如图7
10、测试连接，打开 Git Bash 输入：ssh -T git@github.com 。但是在 Git Bash 中执行成功。11、再次执行命令时：git push -u origin master，报错：Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.。12、删除目录：.git，重新提交与推送。报错：remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.。13、打开网址：https://github.com/settings/tokens 。Generate new token，勾选所有权限。如图8
14、编辑远端 URL：https://github.com/shuijingwan/hello_laravel.git ，修改为：https://xxx@github.com/shuijingwan/hello_laravel.git 。删除目录：.git，重新提交与推送。推送成功。如图9
15、查看 GitHub 上的 Git 仓库，确认文件已经成功推送至 GitHub。如图10
