mmm, it seems the most common password was '123456', closely followed by '12345678'. Lots of birthdays and first names and 'godisgreat' type of things. Apparently 2 in 5 people use the same password for everything online. Scary.
My passwords are generally long, often random and all unique. I use password safe to keep track of them. If I lost the encrypted file and backup for that I would constantly hitting the 'I've forgotten my password' buttons . .
