Questions about Admin Mode Exit and SSH Key Confirmation (OnlyKey DUO)

SSH, OpenPGP, GPG

Hi,

I’m using an OnlyKey DUO with firmware version v3.0.4-prodn, and the app version 5.3.6 on Windows 10. The device works well.

I followed the documented steps to load an SSH key:

  • Entered Admin mode by holding button 1 for 10 seconds (LED blinking red).
  • Used the app to load an SSH private key (with embedded public key).
  • The app confirmed that the key was successfully loaded.

However, I have two questions:

  1. How do I properly exit Admin mode?
    I couldn’t find this in the documentation, so I simply unplugged the key.
  2. How can I verify that the SSH key was actually loaded?
    When I press button 2 for 5 seconds to display data allocation, it doesn’t show any used slots.

Thanks in advance for your help!

Yes, that is the correct way, there isn’t a way to exit admin mode you just remove the key when you are finished.

  1. How can I verify that the SSH key was actually loaded?
    When I press button 2 for 5 seconds to display data allocation, it doesn’t show any used slots.

Follow the guide here - OnlyKey SSH/GPG agent | Docs
You will be able to see/export the public key for the slot in use.

Hello T11,

Thanks for your reply. I’ll follow the guide. Since I’m primarily on Windows for professional reasons, I’ll give OpenSSH 8.2 a try.
