5 characters password... lol... the advice has been for at least the past 10 years at least 8 characters...

Just to comment a bit on wallet encryption... this is a joke in itself since it just need to have an old unencrypted wallet to bypass it (I learnt it at my advantage actually because I once forgot the password of some wallet :).

Actually, for my bitcoin wallet, I use a laptop which is offline most of the time and has no other purpose than accessing my wallet (on a fresh install). Actually other alternative would be to use specialized dedicated hardware such as Treasure or some other I forgot the name.
