Say you have your user credientials placed in your web.config . How do you change the passord for a user programatically. Less talk, more code.

Sample web.config in root folder:

<system.web>

<compilation debug="true" />

<authentication mode="Forms"><forms loginUrl="login.aspx" defaultUrl="default.aspx">

<credentials passwordFormat="Clear">

<user name="user" password="user" />

<user name="admin" password="admin" />

</credentials>

</forms>

</authentication>

<authorization>

<deny users="?"/> </authorization>

</system.web>

Code for changing Password:

Configuration webconfig = WebConfigurationManager.OpenWebConfiguration("~");

SystemWebSectionGroup sysweb = (SystemWebSectionGroup)webconfig.GetSectionGroup("system.web");

AuthenticationSection authSection = sysweb.Authentication;

FormsAuthenticationUserCollection users = authSection.Forms.Credentials.Users;

FormsAuthenticationUser user = users["UserName"]; //you can grab it from a textbox or User.Identity.Name ~ current LoggedIn User

user.Password = "newPassword" //you can grab it from a textbox......

webconfig.Save();
