You are right about keeping our security safe from hackers to get access to our accounts and our crypto assets. A seed phrase should be kept safe from third party, no matter how close the person maybe to us we should keep our seed phrase and our pass key safe from them because we don't know other people mindset. Even if you want somebody to have access to your crypto wallet it should be our partner and even at that you should move your crypto assets to a multi signature wallet because you both actually need each other approval before can make any transactions.
Talking about the security of our forum account, I just noticed that we can activate 2-Factors- Authenticator on our account to prevent it from hackers, and you can also set personal questions in case you want to retrieve your Bitcointalk account from hack. But if you want to recover your account with the personal questions your Bitcointalk account will be locked for some weeks before it will be opened.
That is just it my brother, for you not to be hacked from any third party, all needs to do is to keep your seed phrase safe within yourself, and if you you are a newbie you should not allow anyone have access to your seed phrase and you must have Google authenticator on your phone which you can link to your wallet incase if any scammers are trying to temper to your it requires the Google authenticator before any coins can be moved from your wallet to another, and i believe that you as a newbie you can be able to secure your wallet from scammers.
