Thanks for the information but again it can get hacked or password could be stolen. The best is to write in a piece of paper and you keep it locked in your locker or share it with your relatives so that in case you not their still your loved ones can access that exchanges, wallets etc and they can get the money rather than that going waste.
There's a trade-off between security and functionality. This way you can just put one strong password in an envelope and securely store it and pass a copy to your trusted loved ones. Cracking encryption that strong if you didn't use a short password or something susceptible to a dictionary attack would theoretically take years.
It's a personal choice if having the passwords there with an easy copy paste when you need them balances the tiny risk.
Again I stress this is not for private keys seed phrases.
I'm always a bit wary of a method that forces me to copy and paste those passwords every time I want to log-in.
There is malware that is specifically designed to intercept the contents of your clipboard. I do agree that you have to make some kind of trade-off between security and functionality though.
I wonder what the security risks are of just using FireFox's password manager, given that you've set a very strong master password?
You have the benefit that you never have to type in or copy/paste your password, so keyloggers or other malware can't intercept the password that way.
