  Hi pathipati ,

  Could you please explain more about your requirement  ? Do you want to change membership/identity user's password or you want to change windows account user's password ?

  Best Regards,

  Nan Yu

  Hi pathipati ,

  I haven't met the issue  . Where do you put the codes , in global.ascx  ? You can also refer to below links for code sample :

  My above code is working when the AppPool is set to 'LocalSystem' and not 'ApplicationPoolIdentity'. is it harm to set AppPool to LocalSystem

  Hi pathipati,

  Local system has the highest privilege and should avoid , so the problem is the service account was not given the permissions to change/reset passwords if you are using service account with appropriate AD permissions.
