I store them in my notebook and keep it in a secured box. I may left a message in the box saying Dont open this until the day I die, which I want to inherit it to my current and future family members.
I also had a copy of them stored in a Notepad file on my USB. I really dont trust Gmail and Google Docs to store all of my passwords, seed phrases, private keys, etc. Not in my mobile phones, I have learned my lesson the hard way after those screenshots were gone because of forced factory reset. However, I do trust Protonmail as its more secured.
You can also use a password manager for storing your passwords and even keys under some unique usernames that only you can understand when you open, it is a hassle free method and you would only have to remember a single password for that password manager which I think would be an easy process to follow rather than following these methods which I think is pretty risky if your drive falls into wrong or malicious hands.
Isn't that what i said with like using lastpass or keepass? But here you are changing the word a bit?
Example imagine one of your words is your seed is doggy... im not sure if that is even a word or not.
But imagine you type it enhhz... like imagine the word you see... you go one letter ahead of each letter... thoughts on that? But of course you can easily make a mistake like this. Then when you see ephhz, you go back one letter each... but thats bound to make a mistake right?
Someone mentioned about writing it in a book. That does seem like good idea? Imagine a big book and you just gotta remember what page or pages you wrote it? Then you go back to the book?
Still. what about the method i originally mentioned? Type it in keepass... then store it in google drive or dropbox. So only way someone can access it would be hack your email... but they need your master password for keepass? Or if you want to get more extreme, encrypt keepass file itself where you need to enter a password before... u even get a chance to enter a master password for keepass? Surely that would be the safest way to store it digitally?
If you put it in a usb drive, and encrypt it... sure thats good. But what program you use to encrypt your usb drive? So if you encrypt your usb drive, only if someone knows the password, then can open it up right? But its like well you still have to be concern of fire or floods. The method i describe, well you don't have to be concerned about fire or floods. Thoughts on the method i suggested?
