As long as your private keys are safe your bitcoin is safe. Because it is merely impossible to breach into another's wallet without knowing private keys. So keep your private keys safe. Best use offline wallet to ensure security.
I definitely agree with you, since your password to your wallet keys is safe, then you can assure that it can not hacked by the thiefs or hackers or else they have a way to find your keys or they managed to get your social media accounts that where you store and kept your private keys, but somehow this is a less chance to hacked easily.
