• Run the ssh-keygen -t rsa command on both your local computer and the server, pressing Enter to accept all defaults.

In your local computer’s C:\Users\YourUsername\.ssh directory, two files will be generated: id_rsa (private key) and id_rsa.pub (public key).

• Copy the contents of id_rsa.pub and paste them into the ~/.ssh/authorized_keys file on the server.

After this setup, you can access the server using VSCode without entering a password.
