Scared about recent personal information leaks

I'm scared about recent personal information leaks. I once received a notification from Google about an unfamiliar login to my account. Nothing else happened then, but things can happen when you least expect it, so I changed all my passwords. It was a huge hassle. I also received an email from Rakuten Drive official stating a possibility of personal information leak from my Rakuten Drive account… (I logged in through the app, considering the email might be a scam) I deleted my Rakuten Drive account. When I looked into Rakuten, I saw reviews saying their response isn't very good…… It's disappointing because I heavily used them for banking, my smartphone, credit cards, and online shopping. I'm currently in the process of looking for alternatives. As for my smartphone, I really don't want to switch because the 'Anshin Guarantee' (Peace of Mind Guarantee) is incredibly convenient…
