  • Hello,

    For on-premise users you can configure Password Policies in Group Policy and modify password length as required. By default this is set to 7 characters in Default Domain Policy. If I'm correct the maximum length is 127 characters.

    For Office 365 there is a password policy set for minimum 8 and maximum 16 characters.
