DGX Spark initial setup is finished but I cannot access the DGX via SSH, as I don not have the password

The DGX Spark system completed initial setup but I am locked out because no administrator credentials were ever created.
There is no reset button or local console on the DGX Spark.
I need help to reset the device or reinitialize setup.

Unfortunately, if you don’t have the OS password, the only way to recover is by reimaging the OS. Security is working. Admin credentials should be created during the initial setup. System Recovery — DGX Spark User Guide

Yes I know but the OS password was never created during the initial setup - I was never prompted for it. Now the WiFi hotspot of DGX Spark is disabled preventing me from doing the initial setup again.

you will get wifi hotspot again once you initiate the system recovery steps linked above

No other method possible? The recovery process outlined in the DGX Spark User Guide requires a display and a keyboard that I don’t have access to right now.

I’m puzzled by something: user name and password are established during the setup process. I’m not sure it is possible to complete it without specifying an initial user account.

The system should have prompted me during the initial setup to set a password. I never did and that’s why I am stuck in this situation.

Had the same issue after setting up custom hostnames. Here’s what worked:

  1. Check SSH config on your DGX Spark:

    sudo nano /etc/ssh/sshd_config

    If PasswordAuthentication is set to no, change it to yes

  2. Restart SSH:

    sudo systemctl restart ssh

  3. Verify IP and hostnames in /etc/hosts

  4. Reboot the Spark, then quit and reopen NVIDIA Sync

  5. Use static IP when adding device instead of hostname

Fixed it for me. Hope this helps someone!
