I am trying to generate alphanumeric passwords and I did this in web.config:
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="false"
passwordFormat="Clear"
maxInvalidPasswordAttempts="10"
minRequiredPasswordLength="6"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10" passwordStrengthRegularExpression="^[a-zA-Z0-9]*$"/>
But still i get non-alpha numeric characters. please correct me if wrong.
