Note
Il controllo PasswordRecovery fornisce assistenza agli utenti che hanno dimenticato la password. Consente di richiedere un messaggio di posta elettronica contenente una nuova password o la password già associata al nome utente.
Nota Il controllo PasswordRecovery utilizza i servizi di posta elettronica di Internet per inviare le password nuove o recuperate agli utenti. L'invio di password tramite posta elettronica comporta rischi di protezione. È necessario determinare se tali rischi sono accettabili.
Per ulteriori informazioni sul controllo PasswordRecovery e su altri controlli di accesso, vedere Controlli ASP.NET di accesso.
