 </providers>
 </membership>

This is what i'm using for membership...

You can handle this with the Membership's MinRequiredNonAlphanumericCharacters property.

<membership defaultProvider="SqlProvider"
  userIsOnlineTimeWindow = "20>
  <providers>
    <add
      name="SqlProvider"
      type="System.Web.Security.SqlMembershipProvider"
      connectionStringName="SqlServices"
      requiresQuestionAndAnswer="true"
      minRequiredNonalphanumericCharacters="0"
      />
  </providers>
</membership>

• Important note: Microsoft itself spelled it wrong, it's case sensitive and must be spelled minRequiredNonalphanumericCharacters(changed it above). Someone mentioned this as comment below.

You need to create a custom Membership Provider in your web.config and set the minRequiredNonalphanumericCharacters property to ="0".
