Using strong passwords will not hurt you but if your accounts (whatever it is) are being hacked or compromised then it will hurt you so badly.
There are a lot of sites that offer passwords or password generators for to use. Having a password like this for ex. vbT9 LFe7!ZTC0Qm~)~Y will save your day.
You can use the site like https://strongpasswordgenerator.com/ can do the trick. But, if you can’t remember the strong password you generate (even myself cant memorize it) save your password in a secured place. You can save it on your computer (I repeat, your OWN COMPUTER/LAPTOP).
Remember, better safe than sorry.. Don’t let these damn hackers ruin your life.
