Access to the JHPCE cluster is provided via SSH. Typically SSH has depended on standard Unix userid/passwords to authenticate a user. Unfortunately, it is well known that passwords are hopelessly obsolete and we cannot depend on a simple string of characters for protection. To that end, we require that all users use enable 2 Factor Authentication on their JHPCE account. To set up 2 Factor authentication for your account, please refer to our page on 2 Factor Authentication
In addition, we also support the use of SSH public/private key authentication to access your account. SSH key pairs enhance security by verifying that the system you are connecting to the cluster from is a trusted computer. By using ssh key, you can avoid having to use your password to login to the JHPCE cluster. For instructions on setting up ssh keypairs, please refer to our page on SSH keys.
