Creating ssh keys for MAC/Linux

SSH keys allow for improved access to Research Computing clusters by bypassing the need for 2Factor authentication. Adding your public key to the cluster will allow tools such as ssh, putty and others to more quickly and easily connect.

5. Copy the public key

7. Enter the password of your netid
