Great advice!
I managed to use a 256 random digits long passphrase created by a Password saving software programm, a few years ago on my wallet, thinking it would be unhackable.......
It truly is unhackable I still have the coins as we speak unfortunately as soon as I closed the password programm I found out it didn't save the password as I closed the window....
I am now waiting for quantum computers to maybe 1 day solve the passphrase.......
just my 2 cents...... ah noo 5k$
