Update: Found out this is actually a feature if a device PIN is not set (source).
My new OnlyKey Duo seems to stay unlocked all the time, even after I remove it from the USB port and plug it in again, or after I plug it into another device. This can’t be the expected behaviour, right? (My non-Duo OnlyKey certainly doesn’t behave this way.)
Software versions:
- OnlyKey Duo firmware: v3.0.1-prodn
- OnlyKey App (Windows): v5.3.6
I have set up this OnlyKey Duo as follows:
- Factory reset on the OnlyKey Duo.
- Set backup passphrase to the same as my working non-Duo OnlyKey.
- Created a fresh backup of my non-Duo OnlyKey.
- Restored this backup to my OnlyKey Duo.
