You can delete unauthorized (or possibly compromised) SSH keys to ensure that an attacker no longer has access to your repositories. You can also approve existing SSH keys that are valid.

  1. 在任何页面的右上角,单击您的个人资料照片,然后单击 Settings(设置)

    用户栏中的 Settings 图标

  2. 在用户设置侧边栏中,单击 SSH and GPG keys(SSH 和 GPG 密钥)

    身份验证密钥

  3. On the SSH Settings page, take note of the SSH keys associated with your account. For those that you don't recognize, or that are out-of-date, click Delete. If there are valid SSH keys you'd like to keep, click Approve.

    SSH key list

    Note: If you're auditing your SSH keys due to an unsuccessful Git operation, the unverified key that caused the SSH key audit error will be highlighted in the list of SSH keys.

  4. Open Terminal.

  5. 在后台启动 ssh 代理。

    $ eval "$(ssh-agent -s)"
    > Agent pid 59566
  6. Find and take a note of your public key fingerprint.

    $ ssh-add -l -E sha256
    > 2048 SHA256:274ffWxgaxq/tSINAykStUL7XWyRNcRTlcST1Ei7gBQ /Users/USERNAME/.ssh/id_rsa (RSA)
  7. The SSH keys on GitHub should match the same keys on your computer.

    Note: If you're auditing your SSH keys due to an unsuccessful Git operation, the unverified key that caused the SSH key audit error will be highlighted in the list of SSH keys.

  4. Open Git Bash. If you're using Git Shell, which is included in GitHub Desktop, open Git Shell and skip to step 6.

  5. 如果您在使用 Git Bash,请启动 ssh-agent:

    # start the ssh-agent in the background
    $ eval "$(ssh-agent -s)"
    > Agent pid 59566

    如果您在使用其他终端提示符,例如 Git for Windows,请启动 ssh-agent:

    # 在后台启动 ssh-agent
    $ eval $(ssh-agent -s)
    > Agent pid 59566
  6. Find and take a note of your public key fingerprint.

    $ ssh-add -l -E sha256
    > 2048 SHA256:274ffWxgaxq/tSINAykStUL7XWyRNcRTlcST1Ei7gBQ /Users/USERNAME/.ssh/id_rsa (RSA)

Warning: If you see an SSH key you're not familiar with on GitHub, delete it immediately and contact GitHub Support or GitHub Premium Support for further help. An unidentified public key may indicate a possible security concern.
