This page in a nutshell: Failing to use a sensible password can lead to temporary loss of editing access and may lead to permanent loss of privileged access.

All registered users have to log in using a password before they can edit using their usernames. Passwords help ensure that someone does not masquerade as another editor. Editors should use a strong password to avoid being blocked for bad edits by someone who guesses or "cracks" other editors' passwords. Users may access their account's preferences to change their password.
