当我连接到 SSH 隧道时，我需要为我正在访问的计算机提供密码。
我可以给这个连接一个密码吗？
我希望已经提供密码的原因是我计划编写一个.sh连接到许多不同端口的脚本。
值得一提的是，我在我正在访问的机器上设置了私钥/公钥。如果不添加此键，我将立即被扔出盒子。所要求的密码是Apple User密码。

答案1
更好的想法是使用密钥身份验证。首先，您必须在本地计算机上生成公钥-私钥对：
ssh-keygen
并将新的公钥添加到远程服务器：
ssh-copy-id user@host
之后，您将无需密码即可在远程服务器上进行身份验证。
答案2
“Apple 用户密码”是否可能是您的密钥环的密码，该密钥环保存着您正在验证的公钥的私钥？
现在您想使用该密钥对进行身份验证[电子邮件受保护]
因此，要删除该密码，您必须创建一个没有密码保护的新密钥。这可以通过提到的 ssh-keygen 来完成。
另外，您可能想了解一下如何将跳转主机与 ssh-config 一起使用，以防适用于您的本地计算机：https://ma.ttias.be/use-jumphost-ssh-client-configurations/
