因此，基本上，我正在尝试为服务器的一部分创建一个 SFTP 帐户，该帐户不需要 SSH-Key 或 googles-2fa-pam 模块。我的 /etc/ssh/sshd_config 文件中有以下设置：
Match User sharex
PubkeyAuthentication no
PasswordAuthentication yes
AuthenticationMethods password
PermitTunnel no
AllowAgentForwarding no
AllowTcpForwarding no
X11Forwarding no
ForceCommand internal-sftp
ChrootDirectory /home/sharex
这是我的 /etc/pam.d/sshd 文件的底部：
# Standard Un*x password updating.
@include common-password
auth required pam_google_authenticator.so nullok
运行“service ssh status”时出现错误：

当我尝试通过 ssh 登录帐户时：

有谁能帮助我或尝试给我指明正确的方向，因为我不知道我能做什么。如果您需要更多信息（例如配置文件），请在下面回复 :) 谢谢！
答案1
在 /etc/ssh/sshd_config 或 ssh_config 中的 UsePAM yes 后添加此项
AuthenticationMethods publickey,keyboard-interactive
