Users often create passwords that use common local words such as a school, sports team, or famous person. These passwords are easy to guess, and weak against dictionary-based attacks. To enforce strong passwords in your organization, Azure Active Directory (Azure AD) Password Protection provides a global and custom banned password list. A password change request fails if there's a match in these banned password list.

We've covered procedures that enable you to do controlled testing of Azure AD Password Protection's password validation behavior. Resetting user passwords from the command line directly on a domain controller may seem an odd means of doing such testing, but as described previously it is designed to produce repeatable results. As you are testing various passwords, keep the [password evaluation algorithm](concept-password-ban-bad.md#how-are-passwords-evaluated) in mind as it may help to explain results that you did not expect.
Users often create passwords that use common local words such as a school, sports team, or famous person. These passwords are easy to guess, and weak against dictionary-based attacks. To enforce strong passwords in your organization, Azure Active Directory (Azure AD) Password Protection provides a global and custom banned password list.
