如何禁用 ssh 密鑰並使用密碼登錄

我遇到了一個棘手的情況。首先，我通過密鑰設置了 ssh 訪問，但我忘記了“密鑰”的密碼，然後我無法連接。我嘗試使用另一台電腦登錄，我想我會使用使用者名和密碼登錄。但這就是我得到的-

我只是想知道如何禁用使用密鑰並使用“使用者名”和“密碼”登錄 ssh？然後我可以清理所有東西……

我認為您不能 - 您在“可以繼續的身份驗證”部分中看不到密碼或鍵盤互動。您需要通過控制台連接並對其進行整理。您的 ssh 守護程序不允許密碼驗證（即不為您提供機會）。

您必須通過其他方式登錄到這台機器（例如通過控制台）並設置

PasswordAuthentication yes

在你的 sshd_config
