Enforcing Two-factor Authentication on NEMO

Published: 11 Oct 2023 by NEMO Team

UPDATE 21.11.2023: We will enforce 2FA logins on login2 on 29.11.2023 and on login1 11.12.2023.

UPDATE 13.11.2023: We will inform you in the next few days when this will be the case. We need to fix a problem first.

UPDATE 03.11.2023: We will enforce 2FA logins on login2 on 13.11.2023 and on login1 2 weeks later on 27.11.2023.

As previously announced, we are testing 2FA for logins on NEMO. This feature will be enforced on all login nodes on NEMO in November. We will enforce 2FA logins on login2 on 06.11.2023 and on login1 2 weeks later on 20.11.2023.

If you want to test your login, please use vis1.nemo.uni-freiburg.de and vis2.nemo.uni-freiburg.de. If you need a SSH login without a second factor, please contact us (Support NEMO).

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

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.
