Setting up new Apple ID, I keep getting message that password is not complex enough I have chosen a password that has one upper case, lower case and 3 numbers,  but I still keep getting a message that it's not complex enough.  Why?
According to Apple's support site

Strong passwords
Apple policy requires you use strong passwords with your Apple ID. Your password must have a minimum of 8 characters, not contain more than 3 consecutive identical characters, and include a number, an uppercase letter, and a lowercase letter.
