Testing Two-factor Authentication on NEMO

Published: 8 Aug 2023 by NEMO Team

UPDATE: 09.08.2023: OTP is now enabled for password and SSH key logins.

We are currently testing two-factor authentication for NEMO logins. Currently, this security feature can be tested on our vis1/2 visualization nodes for password logins.

Please visit https://login.bwidm.de/user/twofa.xhtml to generate a new token if you do not already have one. If you have already generated a second factor on https://login.bwidm.de for bwUniCluster or JUSTUS2, you are good to go. See https://wiki.bwhpc.de/e/Registration/2FA for more information.

In the coming weeks and months, we will extend this to NEMO login nodes. We hope to be able to secure SSH keys with OTPs as well, but currently the SSH server version is too old to support some of the needed functionality.

NEMO2 has officially launched, transitioning from a testing phase to full production with expanded hardware, including AMD Instinct MI300A and Nvidia L40A nodes. NEMO1 is being phased out, with limited resources available until May 31st. Users are encouraged to transition to NEMO2 and consult the wiki for details.

NEMO2 uses Miniforge for conda environments, offering a streamlined setup with conda-forge as the default repository. The Miniforge module auto-initializes conda, simplifying environment activation without modifying shell profiles.

The AMD Genoa, Machine Learning and AI partitions for NEMO2 were delivered on December 4th. The acceptance of the storage has been delayed, so that NEMO2 could not yet start this year. However, calculations with the Milan nodes in NEMO1 are still possible.
