What worse case scenario given then fact I have only 14$ on this wallet and of course not intend to deposit anymore funds to that wallet
Are you kidding us here? I believe you already know the answer to the question you asked, and I don't even know how this bypassed me for almost 2 weeks. Well, in this case, I consider it as having your little money in the bank account with the ATM delivered to another person. For the fact that the money is little and you can do away with it, of course, it can't give you a sleepless night. This is especially true if you are such that is financially free, it will just be such that you may not even think it exists. There are some monies in some wallets I forgot they are in there, and this also happens to some money in my bank account as well, once they are little, my mind is off it.
So, letting someone know the passcode to a wallet with just $14 in it, even as you've determined not to fund the wallet again, is nothing at all. Some people could be trusted as well and will not touch that money for any reason. The confusion is that you did not explain your relationship with the person or state if such is just a random person or a hacker, regardless, make your plan good, and never make the mistake of funding that wallet again. We are all susceptible to error.
