While password managers make it easier to store and manage passwords, they are still online platforms that remain highly susceptible to leaks or hacking by unauthorized parties. Even though these services often claim their systems are secure and encrypted, we can never truly know how hackers might exploit a vulnerability to gain access to our passwords.
For this reason, I've always been skeptical about using password managers. How can you trust a single tool to store all your passwords? It just doesn't feel right to me.
I have never used them and that's why passwords shouldn't be shared. But for their purpose as password manager, they're giving some ease to people that manages a lot of accounts from several services and emails. I don't use them either and I know that any of the online tools that we use, they're susceptible to any attack. And when they do, we don't know if they're already attacked and data is stolen already from them.
