我创建了这样的密钥对：
ssh-keygen -t ed25519 -C "my key to go to X" -f ~/.ssh/keyname
然后将其添加到我的.ssh/config
# Name
Host name login.name.com
User USERNAMEHERE
Hostname login.name.com
IdentityFile ~/.ssh/keyname
PreferredAuthentications publickey,password
Port 8001
ServerAliveInterval 120
ServerAliveCountMax 5
我将keyname.pub放入了遥控器的.ssh/authorized_keys
...
ssh-ed25519 AAAAC3NzaC1lZD...XxQlAX my key to go to X
在远程：chmod 600 .ssh/authorized_keys和chmod 700 .ssh
现在我仍然被要求输入USERNAMEHERE的密码...登录到ssh -vvv name（我无法解密）：
╍ᗇ ssh -vvv name

您使用了错误的密钥文件。日志显示如下：
debug2: key: /Users/myname/.ssh/name (0x7f93396034b0), explicit
但是您在.ssh / config文件中指定了〜/ .ssh / keyname。
