How do I add another ssh key to access the GitLab repository

You can use the ~/.ssh/config file to setup the key file (through identifyFile) for authorizing the host that you want to access. Here is the procedure.

Setup

Step 1: Select [Deploy key ] from gitlab

Step 2: Create key by using ssh-keygen with another key file name

Step 3 Setup the ssh config

File: ~/.ssh/config

Host           project1-host HostName       192.168.1.2 IdentityFile   C:\Users\<user name>\.ssh\id_rsa User           <user name> Host           project2-host HostName       192.168.1.2 IdentityFile   C:\Users\<user name>\.ssh\id_rsa_2 User           <user name>

Usage

# Use the first key for access project 1 ## Replace  git clone git@192.168.1.2:<user name>/xxx.git ## to this  git clone git@project1-host:<user name>/xxx.git

# Use the second key for access project 2 ## Replace  git clone git@192.168.1.2:<user name>/xxx.git ## to this  git clone git@project2-host:<user name>/xxx.git
