Every newly set password must meet the complexity rules. A password

  • must be at least 10 characters long,

    • the upper case letters A-Z,
    • the lower case letters a-z,
    • the digits 0-9,
    • the special characters !"#$%&'()*+,-./:;<=>?\[]@^_`{|}~ and the space character,
    • characters that are neither upper case nor lower case, e.g. Chinese and Japanese characters.
