Storing a password is similar to storing a seed. You should never use third parties to save it. It should be saved on paper in a safe place and not stored on a computer or the Internet.
I'm using a password manager but I have a trick on my own on every saved password I just make sure before I hit save the password in the password manager I have inserted two characters in the beginning and also two characters at the end of the password that 4 characters I remember by heart, so even if there is a breach those passwords are useless as they need those 2 characters in the first and the last password I'm fully aware of those breach in the password manager so this is my own innovation to keep the all the password safe.
Very well, this is a good strategy to overcome the problem of password manager hacking, but you must have a good memory otherwise you will get into big trouble.
Although this is a good strategy, with the development of hackers' skills and their use of artificial intelligence, it has become very difficult to trust a third party. It is better to follow the old methods of saving important passwords, I mean writing the password on a piece of paper, and it is also better to hide part of it so that it does not fall into the hands of Unreliable.
