To type upper-row characters, you hold the SHIFT key and press one of any of the keys on the number row of the keyboard (from 1 through 9 and 0). Other settings that can be included in a custom Passfilt.dll are the use of non-upper-row characters. But this policy setting is liberal enough that all users should get used to it. When enabled, the default Passfilt.dll may cause some more Help Desk calls for locked-out accounts, because users are used to passwords that contain only characters that are in the alphabet. The rules that are included in the Windows Server password complexity requirements are part of Passfilt.dll, and they can't be directly modified. This group includes Unicode characters from Asian languages.Ĭomplexity requirements are enforced when passwords are changed or created.
Non-alphanumeric characters (special characters): symbols such as the Euro or British Pound aren't counted as special characters for this policy setting.Īny Unicode character that's categorized as an alphabetic character but isn't uppercase or lowercase. Lowercase letters of European languages (a through z, sharp-s, with diacritic marks, Greek and Cyrillic characters). Uppercase letters of European languages (A through Z, with diacritic marks, Greek and Cyrillic characters). The password contains characters from three of the following categories: So, this user couldn't have a password that included either "erin" or "hagens" as a substring anywhere in the password. Because the second token is only one character long, it's ignored. Hagens" is split into three tokens: "Erin", "M", and "Hagens". Tokens that are shorter than three characters are ignored, and substrings of the tokens aren't checked. If any of these delimiters are found, the displayName is split and all parsed sections (tokens) are confirmed not to be included in the password. The displayName is parsed for delimiters: commas, periods, dashes or hyphens, underscores, spaces, pound signs, and tabs. If the samAccountName is fewer than three characters long, this check is skipped. The samAccountName is checked in its entirety only to determine whether it's part of the password. Neither of these checks is case-sensitive.
Passwords may not contain the user's samAccountName (Account Name) value or entire displayName (Full Name value). When enabled, this setting requires passwords to meet the following requirements: The Passwords must meet complexity requirements policy setting determines whether passwords must meet a series of strong-password guidelines. Describes the best practices, location, values, and security considerations for the Password must meet complexity requirements security policy setting.
