And this can be done outside of SAFE code (might use SAFE as storage) by giving each of your 12+ trusted friends one or two word each of your passphrase and you simply ring them and ask for the word(s).
If done right then no way anyone can reconstruct the passphrase from concluding with others you gave the passphrase to. Maybe if 6 of them did it might become possible to guess it after a while. So best to use friends that don’t know each other
Its most likely you will remember the passphrase you used after contacting one or two of your friends.
Use a phrase out of your will. Then only a few have a copy and they need to know both that you did and which phrase or combination there of you used
