Why do you need password policies on a WordPress multisite network?

A WordPress multisite network consists of a number WordPress websites that can be managed from a central network dashboard. Every website on the network uses the same WordPress core and plugin files as all the other websites on the network, but a number of different tables in the database. One of the main advantages of multisite networks are network users – instead of having users for every websites, a network user can be granted access to all the different sites on the network. For example a user can be an admin one one website and an author on the other.

While network users are a must have feature in large WordPress implementations, they also have a disadvantage: an attacker only needs to guess one users’ password to potentially gain access to multiple websites, or the whole multisite network. Hence why it is imperative to enforce strong password policies on WordPress multisite networks.
