SSH 每次都会询问密码

我的私钥有一个恼人的问题。每次我想要clone or push通过终端或 Tower 应用程序中的 ssh，我必须输入我的密码。

我什至删除并重新创建了 ssh 密钥，并在 Github 上设置了几次密钥，但看起来它的生命周期很短，几分钟后就过期了！

我跟着生成新的 SSH 密钥 https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/创建密钥。最后我跑了ssh-add ~/.ssh/id_rsa它打印出来：

Identity added: /Users/sajad/.ssh/id_rsa (/Users/sajad/.ssh/id_rsa)

重新启动机器后我运行了ssh-add -l检查它是否仍然存在，结果如下：

The agent has no identities.

我怎样才能解决这个问题？我用的是macOS。

My /etc/ssh/ssh_config:

#   $OpenBSD: ssh_config,v 1.30 2016/02/20 23:06:23 sobrado Exp $

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

对于一个非常相似的问题，有一些非常好的解决方案超级用户 https://superuser.com/questions/1127067/macos-keeps-asking-my-ssh-passphrase-since-i-updated-to-sierra and 提出不同意见 https://apple.stackexchange.com/questions/254468/macos-sierra-doesn-t-seem-to-remember-ssh-keys-between-reboots.

基本要点是苹果最近改变了 Sierra 中的一些行为。值得庆幸的是，通过将以下内容添加到您的顶部即可轻松恢复它们~/.ssh/config file:

Host *
  AddKeysToAgent yes
  UseKeychain yes

这应该足以让它开始使用钥匙串来存储/检索您的 SSH 密钥密码。
