Requiring BoilerKey or SSH key authentication on Community Clusters

Link to update at August 14, 2020 3:01pm EDT UPDATE:

Some common questions about this change are posted in the news article on BoilerKey and SSH Key Login to Clusters FAQ.

Link to original posting ORIGINAL:

During Aug 17-20th, 2020, due to immediate security concerns, we will be changing community cluster access to require BoilerKey two-factor authentication (2FA) for all direct SSH or Thinlinc desktop access to each cluster and will no longer support passwords for logging in to those services. SSH will also continue to accept SSH key-based authentication. Users already running an active session will see no impact until they reconnect to the cluster.

Additionally, Jupyter Hub and Rstudio Server continue to accept passwords for access. Cluster gateway portal already uses BoilerKey for authentication and is not changing.

Thank you for your understanding with this emergency measure. As always, please feel free to contact us at with any problems or concerns.

Schedule of Changes:

  • Aug. 17th: Workbench, Scholar
  • Aug. 18th: Brown, Gilbreth
  • Aug. 19th: Halstead, Hammer
  • Aug. 20th: Rice, Snyder, data.rcac
