Thanks. I thought that the more characters the better and to avoid usual words was enough, so I chose the most obscure long word known in a dead language, so obscure that the original speakers of that language never used it. Didn't realise that having just one letter in upper case made such a difference.
Don't understand this hash thing. Surely you don't have to remember the hash? I'd never do it !
When I first had a computer, I chose a date, which was the wedding day and year of the first marriage of Francis I of France. Not very secure, and I had to keep going to an encyclopedia or Google it, every time I forgot it, which was frequently ! LOL
