如何禁用 ssh 密钥并使用密码登录

我遇到了一个棘手的情况。首先，我通过密钥设置了 ssh 访问，但我忘记了“密钥”的密码，然后我无法连接。我尝试使用另一台计算机登录，我以为我会使用用户名和密码登录。但我得到的是-

mylaptap@mylaptop870:~$ ssh -v -p XXXX XXX.XXX.XXX.XX

我只是想知道如何禁用密钥并使用“用户名”和“密码”登录 ssh？然后我就可以清理一切了……

答案1

我认为您不能 - 您在“可以继续的身份验证”部分中看不到密码或键盘交互。您需要通过控制台连接并进行整理。您的 ssh 守护程序不允许密码身份验证（即不为您提供机会）。

答案2

您必须通过其他方式登录此机器（例如通过控制台）并进行设置

PasswordAuthentication yes

在你的 sshd_config 中

答案3

添加-o PasswordAuthentication

ssh -v -p XXXX -o PasswordAuthentication XXX.XXX.XXX.XXX

如果您的服务器允许，您将能够使用密码而不是密钥。
