In this section, you will add your professor's public key to allow them to log in to your Linux VM and run lab checks and perform troubleshooting when needed.

# Using the following command as your '''regular user''', install your professor's public key on to your Linux VM (substitute <professorID> for the actual public key text): <code>echo "<professorID>" >> ~/.ssh/authorized_keys</code>

# On your test terminal, log out and log back in again to check that keypair authentication is still working.
