*they are also being hacked -
LastPass data was leaked not so long ago. I chose the Keepr manager based on a combination of iOS and Chrome app reviews.
1. This is a very informative story, but imho it would have been better to post it to Beginners & Help.
2. I use Bitwarden. It may worth a look.
3. Although I use a good/reputable password manager, I do use 2FA on the websites where I have more than 1 cent worth of coins, I keep my BTC on hardware wallet and I don't keep any seed data stored on places connected to the internet. This "setup" may also worth a thought.
