Before I didn't give much importance to this, I even used a single password for almost 6 accounts. However there was an occasion in which a game in which I have invested a lot of time and some money suffered a massive hacking, luckily it did not affect me but the scare I had made me realize the importance of this, so now I have a different password for each account, no exceptions, in addition to having them physically written down in a notebook.

I am glad that in your case it was nothing serious either.
