What if you forget one of your 25+ random characters passwords? Then how would you get your bitcoins back?
The passwords are stored in KeePass
And KeePass is protected with one Master password which is impossible to guess or bruteforce, but very easy (for me) to remember.
It looks like bd9x2G5!27cjEYd5v6k, but different
I only remember this particular password though. I wouldn't trust myself on having to remember more passwords like that one myself (that's what KeePass is for).
