【问题描述】：

我在 Windows 10 上设置了 OpenSSH 服务器，通过密码登录可以正常工作。然后，我使用 Windows ssh-keygen 生成 ssh 密钥对并将 pub 复制到 C:\Users\user.ssh\authorized_keys。但是，当我尝试登录时，它仍然要求输入密码。

下面是消息。请注意，“WINDOWSBOX”是我将 pub 复制到并希望使用 ssh 密钥登录的远程 Windows 机器。

【参考方案1】：

然后，我使用 Windows ssh-keygen 生成 ssh 密钥对并将 pub 复制到 C:\Users\user.ssh\authorized_keys。

要明确一点：

您在一台计算机上生成密钥 将公钥复制到目标计算机（如“另一台计算机”中）%USERPROFILE%/.ssh/authorized_keys

它可以在同一台计算机上工作，但看起来很奇怪。

确保您已将公钥复制为目标authorized_keys 文件中的一个 行。

【讨论】：

注册机计算机和目标计算机不同，为清楚起见重新编辑。

@user3108468 好的。你检查你的遥控器%USERPROFILE%/.ssh/authorized_keys的内容了吗？
