Once keys are moved to YubiKey, they cannot be moved again! Create an **encrypted** backup of the keyring and consider using a [paper copy](https://www.jabberwocky.com/software/paperkey/) of the keys as an additional backup measure.

**Tip** Set `pinentry-program /usr/bin/pinentry-gnome3` for a GUI-based prompt. If the _pinentry_ graphical dialog doesn't show and you get this error: `sign_and_send_pubkey: signing failed: agent refused operation`, you may need to install the `dbus-user-session` package and restart the computer for the `dbus` user session to be fully inherited; this is because behind the scenes, `pinentry` complains about `No $DBUS_SESSION_BUS_ADDRESS found`, falls back to `curses` but doesn't find the expected `tty`.

## Windows
Windows can already have some virtual smartcard readers installed, like the one provided for Windows Hello. To ensure your YubiKey is the correct one used by scdaemon, you should add it to its configuration. You will need your device's full name. To find out what is your device's full name, plug your YubiKey, open the Device Manager, select "View->Show hidden devices". Go to the Software Devices list, you should see something like `Yubico YubiKey OTP+FIDO+CCID 0`. The name slightly differs according to the model.
