Suppose you or a user reset a password, and one of the following errors comes up. In that case, it means that either you are using a guessable password or that somebody in your organization has enabled Password Protection in your environment, and you are using a banned word.
- Unfortunately, your password contains a word, phrase or pattern that makes it easily guessable. Please try again with a different password.
- “Unable to update the password. The value provided for the new password does not meet the length, complexity, or history requirements of the domain.”
If you are a user, please try a more complex password to circumvent the error. Substituting @ with A, 1 with I, and other widespread ways of changing up a common word will not be counted as “not including a common word”.
If you are an admin, please note the following about this feature. Users often create passwords that use common words based on personal interests or easily rememberable things (e.g. cities, sports teams, celebrities, months, etc.). These passwords are strongly vulnerable to dictionary-based attacks. Azure AD Password Protection, which works either in a “cloud-only” mode or can also synchronize to on-prem, provides a global and custom-banned password list. The global one is maintained directly by Microsoft; the custom one can be modified by the Microsoft 365 / Azure AD admins.
