ASP.Net 2.0 ChangePassword Control

The ChangePassword Control in ASP.Net 2.0 provides the in-built functionality to change the password of authenticated or logged in user. ChangePassword control by default shows input fields for old Password, new password, confirm new password. First to confirm that the user has accessed the page through proper channel via login page, ChangePassword Control takes the old Password to verify the user identity in the database. Next it accepts the new password that is stored into the database after confirmation.

The ChangePassword Control also has a feature to send the confirmation email to the authenticated user that the password has been changed successfully. You can set the properties like BodyFileName, CC, EmbeddedObjects, From, IsBodyHtml, priority and subject to manage the e-mail message. MailDefinition part of the ChangePassword control also uses the values defined in web.config file under mailSettings section of system.net.
