What are your thoughts on password managers?

Let my browser remember all my passwords. If I forget them, I use right click, inspect and change password type to text, who needs a password manager.

Every account is connected to my e-mail. My e-mail is connected to my phone number, so as long as you don't steal my phone, stealing any of my passwords wont help you. Even if you steal all numbers of my debit card, it won't let you do any transactions without phone confirmation thing.

So what now? Why do you still need secure passwords and their manager?
