I can't import an ed25519-sk or ecdsa-sk FIDO2 key on Windows

On Windows 10+, importing discoverable (aka resident) SSH keys from FIDO2 devices and connecting using one requires the administrator privileges.

To start the app as administrator, follow these steps:

  1. Close Termius, if it's currently open.
  2. Right-click the Termius shortcut and choose 'Run as administrator'.

Note: Starting from Windows 10 1909 (18363 build number), Windows requires admin permissions or using Windows Hello for connecting to FIDO2 devices.

    Same problem, using Termius version 7.59.2.
    Tried on Windows 11 and Windows 10. Both computers fully updated, YubiKey and YubiKey Manager working.

    I am unable to import keys too, running as admin user with UAC elevation. I am able to log-in to hosts with security key and generate keys.

    Termius 7.59.7, Win11Pro, Yubikey 5C NFC (FIDO2 PIN configured)

    This does not work on Windows 11. Even with admin privs, Termius just says it needs admin privs.

    Windows 10 Pro: same experience as the rest of the commentors.  Termius says it can't import FIDO due to not running as administrator when running as administrator.

    Problem:
    As per previous comments, I cannot import FIDO2 keys from any of my Yubikey keys.


    Steps to reproduce:

    • Ended all (7) Termius tasks in task manager and verified that there were none running.
    • Ran Termius as Administrator as suggested and verified in Task Manager that the processes are running elevated:


    System:

    Happy to help test any patched version that can fix this issue.

    More than one year and still no solution for this bug/problem?
