So to do away with such persons who may have some negative intensions of you is just to avoid them by keeping your seed phrase privately to your awareness alone and don not share your device which your wallets/accounts is being logged on.
Also, do not be confirmable logging in your accounts with different devices and avoid untrusted online links and sites.
Hey mate, I think you misunderstood the ops question, and mistaken it to mean wallets instead of forum account which is what the ops really want to know how he can protect his forum account from hacker's and intriders, and for that I think you may have to edit your comment and include how he can protect his forum account instead of wallets, because not all wallet requirs password to keep logging in, and no one can hack your Wallet because they know your password, since not all time you input your wallet seed phrase to log in.
And to protect your forum log in details from hacker's, is best that you make sure that you make use of the stay log in feature in the log page of the forum and avoid frequent changing of your browser or using a third party device or browser to long into your account, doing so will protect your account alot.
