hhhhh...maybe you can write all the words in the password in a piece of paper and keep it in a book, which is supposed to be put on the ceiling...will it be safe enough? My advice is that you can't put the words online cause the hackers are skilled and canny

Don't ever attempt storing your private keys or phrases on the internet becasue nothing is ever safe on the said internet. Most computers or other devices on the internet are compromised and if such system be use to store these sensitive information then there will be the opportunity for the hacker getting the sensitive record for exploitation, ensure to keep these sensitive information off-line as the best practice.
