So you store all your passwords in proton password? what if it got hacked? you lose everything

I memorize a "salt" and i DON'T write it into the password manager. This way even if the password manager is hacked, there's still one more step, a hidden cross passwords password ("salt") to guess to hack to all of your accounts.

The problem is, If we want to change the salt, or to even remember which salt exists where -it's difficult.

So it would be amazing to have a dropdown with different "salt" keys and mark every account/password if it have salt key and which one (over time over 100s accounts it takes time to change password with their salt key and can be confusing to know which account have which salt key version).
