Question

Integer part of password should not contain only integer part of the user id means

Answer 1

Integer part of password should not contain only integer part of the user id because then the Id can be accessed easily by any stranger.

Answer 2

"     The question is quite unclear. However, the statement “Integral part of a password containing integers in user id is dangerous” means that the numerical part of the password should not contain the numerical part of the "user ID".

    This can be asked from the user as a security procedure because it might make the password quite obvious and easy to guess just like many websites ask users not to use dictionary words in their password."
