I’m working on the multi-signature and I currently have multiple backup of my seed and talking about how easy it is to guess……my seed is the most rarely guessable seed on the planet earth for it is extraordinary..just that I stored it in my memory and that was why I remembered it that easy.
the curious thing is that when you mention the "seed" it gives the impression that you are referring to the password of the Wallet file, which is incorrect, the seed is one thing and the wallet file another, I deduce this because you say that you found the wallet after 5 years and if you knew the seed by heart you would not need the wallet file, the seed is a phrase composed of a series of words that when you enter them you regain access to your coins without the need for a password, it is the direct link to your funds, so you should store them under lock and key (encrypted) because if you save it in a txt file or something like that without protection you could lose your money, on the other hand, the wallet file is a file where your addresses and other data such as configurations are stored, these may or may not be under a password(be careful).
