我有一个棘手的情况。 首先，我通过键设置了一个ssh访问权限，我忘记了“keys”的密码，然后我无法连接。 我试图用另一台电脑login，我想我会login使用用户名和密码。 但这正是我所得到的 –

我不认为你可以 – 在“可以继续的身份validation”部分中看不到密码或键盘交互。 您需要通过控制台进行连接并进行整理。 你的SSH守护进程不允许密码validation（即不提供你的机会）。
你必须有另一种方式login到这台机器（例如通过控制台）并设置
PasswordAuthentication yes
在你的sshd_config中
添加-o PasswordAuthentication
ssh -v -p XXXX -o PasswordAuthentication XXX.XXX.XXX.XXX
如果你的服务器允许，你可以使用密码而不是密钥。
