3. Remote: On August 13, 2021, support for password authentication was removed. Please use a personal access token instead. Remote: seehttps://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/Learn more. Starting August 13, 2021, we will no longer accept account passwords when authenticating Git operations and will require token-based authentication.
4. Configure two-step verification, refer to the URL:https://docs.github.com/cn/authentication/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication.
5. Reference URL:https://www.jianshu.com/p/9317a927e844. Generate a new SSH key. Open git bash, enter the following command, and then press Enter three times in a row: ssh-keygen -t rsa -c “shuijingwanwq@163.com”. The key holds the path: /c/users/administrator/.ssh. id_rsa is the key and id_rsa.pub is the public key. as shown in Figure 3
Figure 3
$ ssh-keygen -t rsa -C "shuijingwanwq@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
The key fingerprint is:
