Property Value

true if the membership provider supports password reset; otherwise, false.

Password reset is the ability for ASP.NET membership to replace the current password for a user name with a new, randomly generated password when a user has forgotten their password or the current password is no longer valid. This is especially useful when password format is set to Hashed, as users cannot retrieve hashed password values.

The following code example shows the membership Element (ASP.NET Settings Schema) element in the system.web section of the Web.config file for an ASP.NET application. It specifies that the application use an instance of the SqlMembershipProvider and enables password reset.

<membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="20">
  <providers>
    <add name="SqlProvider"
      type="System.Web.Security.SqlMembershipProvider"
      connectionStringName="SqlServices"
      enablePasswordRetrieval="false"
      enablePasswordReset="true"
      requiresQuestionAndAnswer="true"
      passwordFormat="Hashed"
      applicationName="MyApplication" />
  </providers>
</membership>

The following code example first verifies that EnablePasswordReset is true, then resets a users password and returns the new, automatically generated password.
