What does it mean to use a person's birthday name or account number as your qq password?

It is possible to be good friends, but lovers are more likely, because using the other person's birthday as a password means that the other person is very important to you, or you don't have to look for numbers on the keyboard to remember your birthday. If you are not a lover or a friend, why not choose a birthday or a string of numbers that are convenient for you to type? Seek adoption.
