CROSS WIRES

I was in a couple's home trying to fix their internet connection. The husband called out to his wife, who was in the other room, for the computer password.
"Start with a capital S, then 123," she shouted back.
We tried "S123" several times, but it didn't work. So we called the wife in. As she inputted the password, she muttered, "I really don't see what's so difficult about typing Start123."
