Yeah, the security lies on our hands and how we manage our keys in front of other people, from friends, relative members, and most especially, on how we keep it. Not guaranteed to the fullest secured but at least we do something to not getting prone to any hacking sentiments.
And one thing we should do when we make access of our wallet is to use our own gadget, PC, laptop or even the phone. And don't forget to logout.
all that can be ascertained is that if it gets hacked because of our negligence by not being able to pay attention to our key storage properly. I agree not to trust friends, relatives or anyone else, when we have to keep it well. because there will be no guarantee that it can't be hacked.
now there are probably many alternatives to securely locking that we can get to make the best use of it.
always sure we lock it right , we can be sure that we will be safe, but don't forget what our colleague said above to not position anything you use to not leave your job by logging out.
