you literally described the exact use case for password managers. in security, it's not about IF you get breached, it's WHEN and how to recover from it. this includes cloud password managers. you can hack all the data you want from these companies but any reputable password manager company will employ a Zero Trust model where your data is stored encrypted. they can completely upend the company and destroy their whole infrastructure, but they still can't do shit unless they have your master pass or a time machine.
