The private key should be well stored and I saved it offline. And this is very safe because all my friends are not familiar with the crypto. Even to be safer again that my computer uses the passcode. So far I have not-hacking and my digital assets are still safe. And I suggest that never anyone else use your computer's device.
That's true must never to use our computer device those private keys we have. Must better to save on it to USB or any offline device we have, As of now we need to be careful always to our important keys and never share it even if our close friends and family.
