Logging in to Git through SSH can eliminate password verification, simplify switching between different environments, and improve security through SSH key authorization. The specific steps include: 1. Generate an SSH key pair; 2. Add an SSH key to the SSH proxy; 3. Add the SSH public key to the Git server; 4. Test SSH access. Security Tips: It is very important to protect the security of SSH private keys.

How to log in to Git using SSH

Logging in to Git using SSH provides a secure and efficient way to interact with remote Git repositories. Setting up SSH access allows you to:

• Relieve the hassle of authenticating with your password every time
• Easily switch between different computers and accounts
• Improve security with SSH key authorization

step:

1. Generate an SSH key pair

• Run the following command on your local computer:

 <code>ssh-keygen -t rsa -b 4096</code>

• You will be prompted to enter a file path to save the key (default ~/.ssh/id_rsa) and enter the password twice.

2. Add an SSH key to the SSH proxy

• On macOS or Linux:

 <code>eval "$(ssh-agent -s)" ssh-add ~/.ssh/id_rsa</code>

• On Windows:
• First install an SSH agent, such as PuTTY Agent.
• Then add your SSH private key to the proxy.

3. Add the SSH public key to the Git server

• Copy your SSH public key. On macOS or Linux:

 <code>cat ~/.ssh/id_rsa.pub</code>

• On Windows, use the PuTTYgen tool to export the key and copy the public key.
• Navigate to the Git server (or service, such as GitHub) and add it to your SSH key list.

4. Test SSH access

• Try cloning or pushing a remote repository. You should succeed without having to enter your password again. For example:

 <code>git clone git@github.com:username/repository.git</code>

Safety Tips:

• It is crucial to protect the security of your SSH private key.
• Restrict access to private keys.
• Update key pairs regularly for enhanced security.
